## Context
As per PR title - we're pausing the development of the RLS Tester
feature preview while we re-evaluate its direction. Have also updated
the GH discussion
[here](https://github.com/orgs/supabase/discussions/45233) RE this! 🙏

## Context
Just some clean up as I was going through stuff
- `useExecuteSqlQuery` is deprecated and not used at all
- As such `execute-sql-query` is technically irrelevant, the more
relevant file is `execute-sql-mutation`
- Hence opting to consolidate `execute-sql-query` into
`execute-sql-mutation`
- Also removing `ExecuteSqlError` since its just re-exporting the
`ResponseError` type
There's a lot of file changes but its essentially just updating the
importing statements across the files
## Context
Resolves FE-3221
Heavily inspired by what @filipecabaco has done previously here:
https://github.com/supabase/supabase/pull/45360
This PR explores the use of pglite to set up a sandbox for RLS testing,
which will pave the way for testing mutation based queries so to ensure
no disruption to the actual database. Sandbox can be set up within the
RLS tester panel as such:
<img width="500" alt="image"
src="https://github.com/user-attachments/assets/0cfdf8e4-dd99-4dee-ac00-39a32b375c07"
/>
Which the sandbox will mimic the project's database to the bare minimum
required
- entities from the `public` schema are copied over (types, tables,
functions, policies)
- `auth` schema is pseudo setup with `SANDBOX_SETUP_STATEMENTS`
- Enough to support role impersonation + querying tables with references
to the auth schema (e.g users table)
- data is seeded up to 100 rows for each table
- More info RE limitations in the last section below
Once sandbox is ready, you'll see this UI where you can either leave the
sandbox, or re-sync the sandbox from the actual database
<img width="500" alt="image"
src="https://github.com/user-attachments/assets/d07ce55f-5bc8-4722-8ce9-898b9b458f9b"
/>
Changes are currently feature flagged, so won't be available publicly
just yet until things are ironed out and ready
## To test
- [ ] Verify that setting up sandbox works
- [ ] Verify that you can query your sandbox, and queries do not touch
the actual database (can verify that we're not sending HTTP requests to
the /query endpoint)
- [ ] Verify correctness of RLS tester as well, should match correctness
with testing against actual DB
- [ ] Verify that re-syncing sandbox picks up changes
- Can test by updating your policies that will affect the output of your
select query
- e.g SELECT for `authenticated`, change from just `true` to `false`
- [ ] RLS tester should work as per normal (against actual DB) with the
feature flag off with no additional overhead
Let me know of any edge cases you might run into while testing
## Known quirks that will be addressed subsequently
Leaving these for now just to not bloat this PR further
- Pglite schema needs to be re-synced if updating RLS policies while
testing, to ensure that pglite gets the updated policies. Will think
about how to make this more seamless
- Sandbox has its own limitations, will need to add a dialog to inform
users how the sandbox works and what limitations to note of
- e.g only the auth schema is mimicked - so policies that reference
storage helpers won't work (although i think auth is probably the main
use case and the rest might be niche)
- We can slowly expand tho where required
- Eventually we'll also move forward with figuring out testing mutation
queries with this sandbox
