## 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? Docs update. Style only. ## What is the current behavior? The connecting to Postgres guide and its serverless drivers child page have drifted from `WORD_LIST.md` and `CONTRIBUTING.md`. They also carry six defects: - The connection pooling diagram's alt text describes migrations on a preview instance. - The SSL screenshot's alt text and the sentence above it both promise connection info. The image shows the SSL Configuration panel: a toggle and a Download Certificate button. - "Where can you see current connection usage?" lists three Observability reports, then says the Roles page is not real-time. The Roles page appears nowhere else in that answer. - The serverless drivers manual configuration step has no main clause. - "For example, If you set the pool size to 30". - One of the two monitoring queries uses uppercase SQL keywords. Three of the four connection strings use `postgres://` and two carry literal project refs. The Connect dialog emits `postgresql://` with placeholders. The pooler host is templated as `aws-[region]`, which reads as composable and isn't. Hosts are `aws-<index>-<region>.pooler.supabase.com`, and the index is a pooler cluster index, not part of the region. Both `aws-0-us-west-1` and `aws-1-us-west-1` appear in this repo, so a reader can't derive it. Studio doesn't compose the host either; it comes from the API. Groundwork for [DOCS-1312](https://linear.app/supabase/issue/DOCS-1312). The issue stays open until the paired eval is re-run. ## What is the new behavior? Word-level edit. No section is added, moved, or reordered, so the restructure in the next PR of this stack lands as a readable set of moved lines. Headings are untouched; PR 2 owns all heading changes. - Fix the six defects above. - Align the connection strings with what the Connect dialog emits: `postgresql://` on all four, and `[PROJECT-REF]` in place of two literal project refs. - Use `[POOLER-HOST]` in the copyable pooler strings, the convention the newer quickstarts already use. Keep the full `aws-[INDEX]-[REGION]` shape in the summary table, where showing the shape is the point. - Settle on one name per concept: shared and dedicated pooler in sentence case, persistent backend, serverless and edge functions, and paid plans. - Drop bold used for plain emphasis, parenthetical asides, and claims the page doesn't support: "ideal for", "ensures best performance and latency", "satisfactory on their own". - Format the two literal error strings as code, not quotes. - Split the pool size answer into one paragraph per subject, and turn the two pooler limits into a table. - Serverless drivers: sentence case title, an intent sentence, and a four-step procedure in place of the sentence fragment. ## Additional context PR 1 of 2. Base is `master`. Second commit applies review feedback. Third fixes the pooler host placeholder, which belongs here rather than later in the stack: the evidence is in the repo, not in the eval. ## Manual testing 1. Open [Connect to your database](https://docs-git-docs-connecting-to-postgres-style-supabase.vercel.app/docs/guides/database/connecting-to-postgres) on the deploy preview. 2. Read the four connection strings. All four use `postgresql://`, and the two pooler strings use `[POOLER-HOST]` rather than a composable region template. 3. Inspect the two images. The pooling diagram's alt text describes pooling, and the SSL screenshot's describes the SSL Configuration panel. 4. Read "Where can you see current connection usage?". The paragraph after the report list refers to the reports, not the Roles page. 5. Read "What is the difference between client connections and backend connections?". The two limits are a table. 6. Open [Serverless drivers](https://docs-git-docs-connecting-to-postgres-style-supabase.vercel.app/docs/guides/database/connecting-to-postgres/serverless-drivers). Manual configuration is four numbered steps. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **Documentation** - Clarified the PostgreSQL connection guide with updated connection examples, pooling guidance, connection-mode tables, SSL information, FAQs, and SQL formatting. - Replaced sample connection values with generic placeholders in documentation examples. - Added clearer guidance that frontend Data API access requires appropriate RLS policies. - Updated explanations of client/backend connections and long-lived PostgreSQL sessions. - Updated serverless driver documentation with clearer setup guidance for Vercel, Cloudflare, and Supabase Edge Functions. - Reorganized manual configuration into numbered steps and standardized connection string examples. - Improved descriptions of runtime behavior and supported connection methods. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
