Code Review

Todo list

• Gather context (diff, changed files, CLAUDE.md)
• Understand the request (code review only)
• Review pgxntool vendor update
• Review new SQL files (test_factory--1.0.0.sql, test_factory_pgtap--1.0.0.sql)
• Review META.json / control file version bumps
• Post final review feedback

Summary

This PR does two things: pulls in a newer pgxntool release (via the usual squashed subtree commit) and adopts pgxntool's new convention of committing generated versioned SQL files (sql/*--<version>.sql) to git instead of .gitignore-ing them.

Findings

1. Versioned SQL files are correct, unmodified copies. sql/test_factory--1.0.0.sql and sql/test_factory_pgtap--1.0.0.sql are identical to the existing sql/test_factory.sql / sql/test_factory_pgtap.sql (aside from the auto-generated /* DO NOT EDIT */ header), so no logic changed in the extension itself — this is a packaging-only change.

2. Version bump is consistent everywhere it needs to be. META.in.json, test_factory.control, and test_factory_pgtap.control are all bumped to 1.0.0 together (the pgtap sub-extension jumps from 0.1.0 → 1.0.0 to match, which is a reasonable simplification since pgxntool's fixed bug about per-extension versions in default_version — see pgxntool/HISTORY.asc 1.0.0 entry). META.json matches META.in.json. Good consistency.

3. .gitignore was correctly updated to stop excluding sql/*--* now that these files are meant to be committed, matching the new pgxntool behavior described in pgxntool/HISTORY.asc (1.1.0: "pgxntool now assumes versioned SQL files get committed").

4. pgxntool/ changes are vendor/upstream code pulled via the standard squashed subtree commit (b7a3ccee... / commit b7a3ccee), not authored in this repo, per pgxntool/CLAUDE.md ("pgxntool is NOT a standalone project... embedded via git subtree"). I spot-checked the notable fixes mentioned in HISTORY.asc against the code and they're present as documented:

   • pgtle.sh now catches no_data_found and uses ON_ERROR_STOP=1 for psql (matches the 1.1.1 changelog entry).
   • update-setup-files.sh implements the 3-way merge for .gitignore/test/deps.sql described in the 1.1.0 entry, and lib.sh correctly centralizes SETUP_FILES/SETUP_SYMLINKS used by both setup.sh and the new script.
     Since this is vendored, I'd defer detailed line-by-line critique to the upstream pgxntool repo rather than this PR.

5. Minor/cosmetic: META.in.json also updates generated_by email and the repo homepage/bugtracker/repository URLs (BlueTreble → Postgres-Extensions). This looks intentional (org migration) but worth double-checking it reflects where the project actually lives now.

No functional bugs found in the reviewed diff — this is a clean, well-organized packaging/tooling update.
