## Problem
Our `<Button>` component breaks the default `button` contract by
redefining the `type` prop to set its variant (`primary`, `default`,
etc) instead of the button type (`submit`, `button`, etc).
This is confusing and forces to write more code when using it with
shadcn components that expect/inject the standard button props.
## Solution
- rename the `type` prop to `variant`
- rename the `htmlType` prop to `type`
- propagate the changes where necessary
- format code
## How to test
As this is just prop renaming, if it builds it's ok

## What kind of change does this PR introduce?
Refactor
## What is the current behavior?
The Auth policy editor flow still uses the deprecated `Modal` component
and `Modal.Content` / `Modal.Separator` helpers.
## What is the new behavior?
The Auth policy editor flow now uses `Dialog` primitives instead:
- `Dialog`
- `DialogContent`
- `DialogHeader`
- `DialogTitle`
- `DialogSection`
- `DialogSectionSeparator`
Behavior is intended to remain unchanged.

## Summary by CodeRabbit
* **Refactor**
* Updated the policy editor and review flows to a unified dialog layout
for a cleaner, more consistent UI.
* Sections and footer controls were reorganized for clearer grouping and
improved button placement.
* Existing behaviors (viewing templates, review/save flow, and close
confirmation) are preserved.

[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.
YES
## What kind of change does this PR introduce?
Refactor + bug fixes (part of the SafeSql migration stack — PR 2 of 7,
stacks on top of #45897).
## What is the current behavior?
- `pgMeta.columns.create` and the table-editor SQL builder take column
type as a string with array suffix and schema baked in (e.g.
`'private.test_enum'`, `'int4[]'`).
- The studio table-editor SQL emits the legacy schema-embedded `format`
string for enums in non-public schemas, while the pg-meta columns SQL
already returns the new shape (bare `format` + separate
`format_schema`). The two queries disagree on how to represent the same
column, surfacing as a false-positive type mismatch in the FK selector
when both ends are an enum from a non-public schema.
- The FK selector compares column types by `format` alone — same-named
enums in different schemas appear equal, and arrays vs. scalars of the
same base type pass the family check.
- `displayColumnType` renders arrays as the raw `_typname` pg-meta emits
(e.g. `_int4` instead of `int4[]`).
## What is the new behavior?
**pg-meta**
- Introduce `ColumnTypeRef` (`{ schema?, name, isArray? }`) for column
type input, replacing the legacy string-with-array-suffix format.
`pgMeta.columns.create` and the table-editor SQL builder consume the new
shape.
- Add `format_schema` to the column zod schema; pg-meta SQL emits the
type's schema for the table editor's ColumnType dropdown.
- `pgMeta.columns.create` returns a `SafeSqlFragment`.
- Studio table-editor SQL now emits bare `format` + `format_schema`,
matching pg-meta's columns SQL.
**Studio**
- `SafePostgresColumn`/`SafePostgresTable` extend the new `PG*` types
(master dropped postgres-meta).
- Pipe `ColumnTypeRef` through `SidePanelEditor` → `ColumnEditor` →
`TableEditor`, along with the column-create mutation, table
retrieve/list queries, and the `TableList`/`ColumnList` surfaces.
- `displayColumnType` helper renders arrays as `type[]` (or
`schema.type[]`) and handles non-implicit schemas.
- FK selector now carries `sourceIsArray`/`targetIsArray` and compares
the full `(format, format_schema, isArray)` triple. Family checks for
numeric/text/uuid skip when either side is an array (FKs across array
boundaries are never compatible).
- Type-mismatch and type-notice alerts pass `isArray` to the display
helper.
- Bundle `Policies.utils` + `Policies.types` + `sql-policy-mutation`,
`PolicyEditorModal`, and `SchemaGraph` here because `SidePanelEditor`
consumes `acceptGeneratedPolicy`/`AcceptedGeneratedPolicy` — splitting
requires temporary overloads with no architectural payoff.

### Manual test checklist
Surfaces touched by this PR — please exercise each:
**Table editor**
- [x] Create a new table with a mix of column types (scalar, array,
enum, foreign key)
- [x] Add a column to an existing table; verify the type dropdown lists
scalars + arrays separately and shows schema-qualified names for
non-public enums
- [x] Edit an existing column's type (scalar ↔ array, switch between
enums in different schemas) and save
- [x] Verify enum types from a non-public schema (e.g.
`private.my_enum`) display as `private.my_enum` in the column list
**Foreign key selector**
- [x] Open the FK selector for a column and pick a target column with a
matching type — no mismatch warning
- [x] Pick a target column whose type differs only by schema (two
same-named enums in different schemas) — should show a type-mismatch
alert
- [x] Pick a target column where one side is an array and the other is a
scalar of the same base type — should show a type-mismatch alert (no
auto-cast across array boundary)
- [x] When FK target sets the column type, verify `format_schema` and
`isArray` are preserved on the source column
- [x] Type-mismatch and type-notice alert messages render array types as
`type[]` (not `_type`)
**Column list / table list**
- [x] Schema-qualified type names display correctly for columns whose
type lives in a non-public schema
- [x] Array columns display as `type[]` (or `schema.type[]`)
**Policies (bundled due to import dependency)**
- [x] Open the Policies page; create/edit/delete a row-level policy via
the modal
- [x] Generate a policy via the AI assistant and accept it through
`SidePanelEditor` — verify the accepted policy lands in the editor
correctly
**Schema visualizer**
- [x] Open the Schemas → Schema Visualizer page; verify it renders
without type errors and shows tables/relationships

## Summary by CodeRabbit
* **Improvements**
* Support for column types in non-public schemas and richer column type
presentation (includes schema and array info).
* Stronger SQL safety around policies and constraints; draft policy SQL
is now promoted explicitly on save.
* Improved foreign-key type validation and compatibility checks using
enhanced type metadata.
* **Tests**
* Updated snapshots and tests to reflect new column metadata and SQL
fragment handling.

## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.
YES
## What kind of change does this PR introduce?
Refactor / dependency cleanup.
## What is the current behavior?
`apps/studio` lists both `@supabase/pg-meta` (workspace package) as a
runtime dep and `@supabase/postgres-meta` (external npm package,
`^0.64.4`) as a devDependency. The external package is used only for
type imports across 44 files — there is no runtime usage and no codegen
pipeline that needs it.
## What is the new behavior?
Every `Postgres*` type import (`PostgresTable`, `PostgresColumn`,
`PostgresPolicy`, `PostgresTrigger`, `PostgresView`,
`PostgresMaterializedView`, `PostgresForeignTable`, `PostgresSchema`,
`PostgresPublication`, `PostgresRelationship`, `PostgresPrimaryKey`) is
replaced with its `PG*` counterpart from `@supabase/pg-meta`, and the
external dep is removed from \`apps/studio/package.json\`. Top-level
type re-exports were added to \`packages/pg-meta/src/index.ts\` so
consumers can import directly from the package root.
Two latent issues surfaced by the stricter pg-meta types are also fixed:
- \`data/foreign-tables/foreign-tables-query.ts\` was casting
foreign-table results as \`PostgresView[]\`; corrected to
\`PGForeignTable[]\`.
- \`pg-meta\`'s \`PGTrigger\` Zod schema declared
\`orientation\`/\`activation\` as \`z.string()\`, inconsistent with
pg-meta's own \`getDatabaseTriggerUpdateSQL\` helper that requires the
narrow literal unions; tightened to \`z.enum\`.
## Additional context

## Summary by CodeRabbit
* **Chores**
* Updated internal TypeScript type definitions across the codebase to
use the latest type system from `@supabase/pg-meta`.
* Removed `@supabase/postgres-meta` dependency.
* Enhanced type validation for database triggers and schemas to enforce
stricter constraints.

## What kind of change does this PR introduce?
Refactor / security improvement
## What is the current behavior?
SQL fragments across Studio are built from plain `string` values with no
type-level distinction between developer-authored SQL, DB-sourced
identifiers, and user-typed or externally-influenced content.
## What is the new behavior?
Extends the safe SQL model to additional Studio interfaces, using
`SafeSqlFragment`, `safeSql`, `ident()`, `literal()`, `untrustedSql()`,
and `acceptUntrustedSql()` from `@supabase/pg-meta/src/pg-format`:
- **Policy editor**: template constants typed as `SafeSqlFragment` via
`safeSql` tagged literals; Monaco editor `onInputChange` emits
`untrustedSql()`; `acceptUntrustedSql()` called only at the Save
gesture; roles selector emits a composed `SafeSqlFragment` via `ident()`
+ `joinSqlFragments()`
- **Auth hooks**: grant/revoke SQL statements use `ident()` for schema
and function names
- **Docs description editor**: `COMMENT ON` queries use `ident()` and
`literal()` for table/column/function names and values
- **Cron jobs**: `cron.schedule()` call and HTTP request builder use
`literal()` for all user-provided values
- **GraphQL linter CTA**: `REVOKE` statement uses `ident()` for schema,
table, and role
- **Storage public bucket warning**: `DROP POLICY` uses `ident()` for
policy name
- **View security autofix modal**: `ALTER VIEW` uses `ident()` for
schema and view name
- **API settings**: `CREATE SCHEMA` mutation uses `safeSql` tagged
literal
- **Database event trigger delete**: `DROP EVENT TRIGGER` uses `ident()`
for trigger name
- **Database queues query**: queue list query uses `safeSql` tagged
literal
- **Role impersonation**: function invocation SQL uses `ident()` and
`literal()`
## Manual testing checklist
- Authentication > Policies
- Authentication > Hooks
- Integrations > Queues
- Database > Event Triggers
- Integrations > Cron Jobs
- Table Editor > View entity security autofix
- API Settings > expose schema
- Linter > GraphQL exposure CTA
- Docs > table/column description editor
- Role impersonation (user impersonation panel)

## Summary by CodeRabbit
* **Refactor**
* Replaced ad-hoc SQL string building with a safer, fragment-based SQL
construction across auth, policies, integrations, storage, and DB
operations to improve SQL safety while preserving behavior.
* **Bug Fixes / UX**
* Policy editor and code editor now propagate role and input changes
more reliably, improving editor responsiveness and policy handling
without UI changes.

## What kind of change does this PR introduce?
Form handling improvement.
## What is the current behavior?
https://github.com/supabase/supabase/pull/43201/ standardised our
discard changes behaviour with a shared hook and
`DiscardChangesConfirmationDialog` component. But many forms and sheets
still:
1. Don’t have any Discard-confirm close behaviour, making it too easy to
make accidental discards
2. Use a more complicated, manually-created `CloseConfirmationModal`
approach
## What is the new behavior?
- Replaced all instances of `#2` above that had `CloseConfirmationModal`
with `DiscardChangesConfirmationDialog` and its hook
- Improved design system documentation around dirty form dismissal
