Part 2 of a 5-PR stack on `apps/docs/content/guides/database/tables.mdx`. Builds on #50021. ## Problem Four structural problems, all covered by the Guides section of CONTRIBUTING. **Views was a second topic living inside a guide about tables.** Roughly 180 lines, its own subsections four levels deep, sharing nothing with the tables above it beyond the word "table". **The page didn't say what it was for.** It opened with three paragraphs and a sample table before a reader could tell whether the page matched their goal. CONTRIBUTING asks a guide to begin with a sentence declaring its intent. **The top level mixed information types.** It was a flat list of every task, so "Schemas" and "Primary keys" sat beside "Creating tables" and background interrupted the action path. **Reference material interrupted the procedure.** A 44-row data type table sat between "Creating tables" and "Loading data", so a reader following the action path walked through it. Plus a duplicate video: the Dashboard tab under "Joining tables with foreign keys" embedded the same YouTube ID that frontmatter already serves as the table of contents video. ## Solution Moves and regrouping. - **Views moves to its own page**, `guides/database/views`, with its headings promoted one level and the two view-related links from Resources moved with it. - The page opens with an intent sentence, then a section outline, then a "What is a table?" section holding the definition and the spreadsheet comparison. - The remaining sections split into three groups by information type, ordered procedures, context, reference: **Creating and managing tables** holds creating, loading, and joining; **How tables are organized** holds primary keys, relationships, and schemas; **Reference** holds the data type table. - "Joining tables with foreign keys" held both classes, so it splits. The steps keep the heading and stay in the procedures group. The concept, what relational means and the diagram showing it, becomes **Relationships between tables** in the context group. The two cross-reference each other. - The duplicate video goes, and with the Dashboard tab empty the surrounding `Tabs` wrapper goes too. ## Anchors **Every heading keeps its text, so every anchor keeps its slug.** Demoting a heading changes its level, not its anchor. That matters because the inbound links are mostly outside `apps/docs`: Studio deep-links to `#data-types` from three components and `#primary-keys` from two, and `apps/www` links to `#creating-tables` and `#joining-tables-with-foreign-keys`. `#views` is the one exception, since that content left the page. Its single inbound link, in `guides/ai/engineering-for-scale.mdx`, now points at the new page, and both `NavigationMenu.constants.ts` entries are updated: the existing item becomes "Managing tables and data" and a "Views" item sits beside it. ## One deletion that isn't a move The "Columns" heading and its one sentence, "You must define the data type when you create a column." The heading held only the two subsections that moved out, and the sentence repeats a line 50 lines above it. ## Deferred Reordering "View security" behind an access-control foundation. That move only reads correctly once the foundation exists, so it travels with that content in #50024. ## Manual testing Preview: https://docs-git-docs-tables-structure-supabase.vercel.app/docs/guides/database/tables 1. Open the preview. The page opens with its intent, then a four-entry outline, then "What is a table?". Each outline link resolves, and the three groups below read as procedures, then context, then reference. 2. Open `#data-types`, `#primary-keys`, `#creating-tables`, and `#joining-tables-with-foreign-keys` on the preview. All four still land on their sections. 3. Open https://docs-git-docs-tables-structure-supabase.vercel.app/docs/guides/database/views. The new page renders, and "Views" appears in the sidebar beside "Managing tables and data". 4. Run `pnpm build:guides-markdown` from `apps/docs`. It generates 782 files, one more than before. Discard the change to `public/markdown/manifest.json`, which the repo commits as `[]`. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **Documentation** - Added a dedicated guide covering Postgres views, including creation, querying, security options, and materialized views. - Reorganized the Tables and data guide with clearer sections, navigation links, table organization details, and reference information. - Updated the many-to-many example to display SQL directly. - Split database navigation into separate “Managing tables and data” and “Views” entries. - Added a PostgreSQL log configuration entry and a C# client reference link. - Updated documentation links to point to the new Views guide. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
