## Problem
When the table editor showed a "Failed to load tables" or "Failed to
load schemas" error (for example, when the underlying database or API
gateway is unhealthy), there was no working way to restart the project
from that error state. Restarting only worked by navigating to Project
Settings.
## Fix
"Failed to load tables" goes through the existing `ErrorMatcher`
classification system, which only showed troubleshooting steps
(including a restart action) for connection-timeout errors. Added an
`ERROR_MAPPINGS` entry for the unclassified/generic API error case,
reusing the existing `RestartDatabaseTroubleshootingSection` and
`RestartProjectDialog` components already used for connection timeouts.
"Failed to load schemas" (in the shared `SchemaSelector`, used across
the table editor and several Database pages) only offered a retry. Added
a "Restart database" button next to it, wired to the same
`RestartProjectDialog`.
## How to test
- In the table editor, trigger a table-load failure that isn't a
connection timeout (any generic API error). The error card should now
show a "Try restarting your project" step with a working restart action.
- Open the schema selector while schemas fail to load (e.g. mock a 503
from the schemas query). A "Restart database" button should appear next
to "Reload schemas" and open the restart confirmation dialog.
-
`apps/studio/components/interfaces/ErrorHandling/ErrorMatcher.test.tsx`
and `apps/studio/components/ui/SchemaSelector.test.tsx` cover both
cases.

## Summary by CodeRabbit
* **New Features**
* Added database restart guidance when schema loading fails.
* Added options to reload schemas or restart the database, including a
confirmation prompt.
* Added troubleshooting guidance for unclassified table-loading errors.
* **Bug Fixes**
* Improved error handling by displaying relevant fallback guidance for
unknown errors while preserving classified troubleshooting instructions.

Hides the "Multigres" term from user-facing surfaces — it's the tech
powering High Availability projects, but "High Availability" is the only
term users should see for now (per Slack discussion with Saxon/Ivan).
**Changed:**
- High Availability badge hover card (project overview) no longer says
"Driven by Multigres"
- Project creation HA toggle description drops the Multigres name +
multigres.com link, keeps the informational copy
- All schema dropdowns now hide the `multigres` schema on HA projects,
by wiring in the previously-unused `filterSchemasForHighAvailability`
helper:
- `SchemaSelector` (shared — Table Editor, Functions, Indexes, Triggers,
Schema Visualizer, etc.)
- `ExposedSchemaSelector` (API settings → exposed schemas)
- `EnableExtensionModal`, `CreateIndexSidePanel`, `ForeignKeySelector`,
`WrapperTableEditor`, Integrations install sheet `AdvancedSettings`
- SQL editor schema autocomplete (`useAddDefinitions`)
- Schema list computations in the touched components are now memoized
(incl. stabilizing `SchemaSelector`'s `excludedSchemas` default so the
memo actually holds)
**Added:**
- Unit tests for `filterSchemasForHighAvailability` /
`resolveHighAvailability`
- MSW component test for `SchemaSelector` asserting `multigres` is
hidden on HA projects and still shown on non-HA projects
The filter is HA-gated on purpose: a self-hosted/non-HA user with their
own schema named `multigres` still sees it. The flag-gated Multigres
option in Logs is intentionally untouched — that exposure is kept for
the Multigres team's debugging (separate track).
## To test
- On an HA project (`high_availability: true`): hover the High
Availability badge on project overview — no "Multigres" mention; open
schema dropdowns in Table Editor / Database pages / SQL editor
autocomplete — no `multigres` schema
- Project creation with HA entitlement: toggle description has no
Multigres wording/link
- On a non-HA project: schema dropdowns behave as before

## Summary by CodeRabbit
* **Improvements**
* Made schema dropdowns and related selectors high-availability aware
across extensions, indexes, integrations, SQL editing, API exposed
schemas, and relationship editors.
* Updated project high-availability UI text and badge hover description
to remove outdated branding and clarify horizontally scalable Postgres
architecture.
* **Tests**
* Added coverage to ensure the schema “multigres” option is hidden/shown
correctly based on high availability, and validated high-availability
value handling.
