What

Refreshes the series opener improving-query-performance-using-indexes-1-zuLNZwBkuL (Sep 2022), continuing the series refresh started with part 2 in #8029. Part 3 (hash indexes) follows separately. Reviewed and approved by Martin on localhost.

Changes

  • Answer-first lead defining a database index in the first sentence, with series links to parts 2 and 3
  • Updated (July 2026) callout + updatedAt frontmatter (fundamentals are version independent; points to part 2's measurements verified on Prisma ORM 7.8 / PostgreSQL 17)
  • FAQ section as <Accordions> toggles (4 questions, bodies server-rendered)
  • Inline "Overview" TOC removed; the layout renders its own InlineTOC (part 2 still carries one and will get the same two-line sweep with part 3)
  • Link conventions: Prisma Postgres mention → docs; non-canonical Twitter link removed; Josh Berkus credited as former PostgreSQL core team member with the embed identified as Prisma's own meetup recording
  • metaDescription trimmed to ~155 chars; copy fixes (spacing, "SQL Server")

All 8 external links verified 200; rendered output checked against the served HTML (FAQ bodies present, no inline TOC).

🤖 Generated with Claude Code

Fix grammatical error in the "value" bullet.

The bullet starts with "and," which doesn't read correctly in a list context. It should describe the value directly.

✏️ Proposed fix
 - **value**: and a pointer to the record in the specific table
+- **value**: a pointer to the record in the specific table

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Fix subject-verb agreement for "Full-text indexes".

"Full-text indexes" is plural, so "enables" should be "enable".
