What’s Changed

MigraDiff now diffs COMMENT ON metadata across all major PostgreSQL object types — tables, columns, views, materialized views, functions, sequences, types, indexes, constraints, and schemas.

Why this matters

If you store schema documentation, AI context, or compliance metadata in COMMENT ON blocks, MigraDiff no longer silently drops it during migrations. Added, changed, and removed comments all generate the correct COMMENT ON (or COMMENT ON ... IS NULL) SQL.

AI integration

--explain and --generate now read your COMMENT ON metadata as schema context. The AI knows not just that a column is text, but what it’s for — richer explanations, more accurate generated migrations.

Works everywhere

  • Live connections: queries pg_catalog.pg_description directly
  • --from-file mode: works automatically with pg_dump output
  • --output json: all comment changes classified as safe risk

190 tests passing. No new dependencies.
