3dffdefd6e fix(docs) Resolve 196 mdx lint warnings for just, quickly, actually, PostgreSQL (#47358)
Closes DOCS-1057
Contributes to DOCS-1052

## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.

YES

## Problem

We have hundreds of MDX lint warnings in our docs going against style
best practices.

## Solution

Remove and replace in context the following:

- PostgreSQL. There was only one. There was concern about exceptions,
but I found none.
- Just
- Quickly
- Actually

### What changed

Edits follow the [Google developer documentation style
guide](https://developers.google.com/style): concise, direct, active
voice. The flagged words were removed when the sentence still read well,
or replaced when meaning needed to be preserved.

### Common patterns

| Flagged word | Approach | Example |
|---|---|---|
| **just** (filler) | Removed | "you just installed" → "you installed" |
| **just** (limiting) | **only** | "just one row" → "only one row" |
| **just like** | **like** / **the same as** | "function just like
regular users" → "function like regular users" |
| **not just** | **not only** | "not just errors" → "not only errors" |
| **quickly** (performance) | **efficiently** or removed | "find rows
quickly" → "find rows efficiently" |
| **quickly** (time) | **soon** / **rapidly** / removed | "expires too
quickly" → "expires too soon" |
| **actually** (filler) | Removed | "actually execute" → "execute"; "is
actually the most common" → "is the most common" |

## Tophatting

1. See the diff.
2. See that content continues to make sense in context.
3. Locally, `cd apps/docs` and run `pnpm run lint:mdx`.
4. Search for "just," "actually," "quickly", and "PostgreSQL" and see
there are 0 warnings.

## Summary by CodeRabbit

* **Documentation**
* Updated wording across quickstarts, guides, and troubleshooting
articles for grammar, clarity, and consistent step-by-step phrasing.
* Clarified key concepts including Row Level Security policy evaluation
across Supabase products, deferred foreign key constraint behavior, and
when `EXPLAIN ANALYZE` executes queries (and related side effects).
* Refined several troubleshooting instructions and added guidance to cap
log payload size to reduce billed Logs Ingest volume.

This guide shows how to connect your Prisma application to Supabase Postgres. If you encounter any problems, reference the [Prisma troubleshooting docs](/docs/guides/database/prisma/prisma-troubleshooting).
<Admonition type="note">
If you plan to solely use Prisma instead of the Supabase Data API (PostgREST), turn it off in the [API Settings](/dashboard/project/_/settings/api).
</Admonition>
<StepHikeCompact>
<StepHikeCompact.Step step={1}>
<StepHikeCompact.Details title="Create a custom user for Prisma">
- In the [SQL Editor](/dashboard/project/_/sql/new), create a Prisma DB user with full privileges on the public schema.
- This gives you better control over Prisma's access and makes it easier to monitor using Supabase tools like the [Query Performance Dashboard](/dashboard/project/_/advisors/query-performance) and [Log Explorer](/dashboard/project/_/logs/explorer).
<Admonition type="note" title="password manager">
For security, consider using a [password generator](https://bitwarden.com/password-generator/) for the Prisma role.
</Admonition>
</StepHikeCompact.Details>
<StepHikeCompact.Code>
```sql
-- Create custom user
create user "prisma" with password 'custom_password' bypassrls createdb;
-- extend prisma's privileges to postgres (necessary to view changes in Dashboard)
grant "prisma" to "postgres";
-- Grant it necessary permissions over the relevant schemas (public)
grant usage on schema public to prisma;
grant create on schema public to prisma;
grant all on all tables in schema public to prisma;
grant all on all routines in schema public to prisma;
grant all on all sequences in schema public to prisma;
alter default privileges for role postgres in schema public grant all on tables to prisma;
alter default privileges for role postgres in schema public grant all on routines to prisma;
alter default privileges for role postgres in schema public grant all on sequences to prisma;

alter user "prisma" with password 'new_password';

<StepHikeCompact.Details title="Add your connection information to your .env file">
- On your project dashboard, click [Connect](/dashboard/project/_?showConnect=true)
- Find your Supavisor Session pooler string. It should end with 5432. It will be used in your `.env` file.
<Admonition type="note">
If you're in an [IPv6 environment](https://github.com/orgs/supabase/discussions/27034) or have the IPv4 Add-On, you can use the direct connection string instead of Supavisor in Session mode.
</Admonition>
- If you plan on deploying Prisma to a serverless or auto-scaling environment, you'll also need your Supavisor transaction mode string.
- The string is identical to the session mode string but uses port 6543 at the end.

<TabPanel id="serverful" label="server-based deployments">
In your .env file, set the DATABASE_URL variable to your connection string

# Used for Prisma Migrations and within your application
DATABASE_URL="postgres://[DB-USER].[PROJECT-REF]:[PRISMA-PASSWORD]@[DB-REGION].pooler.supabase.com:5432/postgres"

```md
postgres://prisma.[PROJECT-REF]...
```
</TabPanel>
<TabPanel id="serverless" label="serverless deployments">
Assign the connection string for Supavisor Transaction Mode (using port 6543) to the DATABASE_URL variable in your .env file. Make sure to append "pgbouncer=true" to the end of the string to work with Supavisor.
Next, create a DIRECT_URL variable in your .env file and assign the connection string that ends with port 5432 to it.
```text .env # Used in your application (use transaction mode)
DATABASE_URL="postgres://[DB-USER].[PROJECT-REF]:[PRISMA-PASSWORD]@aws-0-us-east-1.pooler.supabase.com:6543/postgres?pgbouncer=true"
# Used for Prisma Migrations (use session mode or direct connection)
DIRECT_URL="postgres://[DB-USER].[PROJECT-REF]:[PRISMA-PASSWORD]@aws-0-us-east-1.pooler.supabase.com:5432/postgres"

Change both your strings' `[DB-USER]` to `prisma` and then add the password created in step 1
