amcheck: Add a test with GIN index on JSONB data

tvondra · tvondra · commit ca738bdc4c9d · 2025-03-29T16:47:44.000+01:00
Extend the existing test of GIN checks to also include an index on JSONB data, using the jsonb_path_ops opclass. This is a common enough usage of GIN that it makes sense to have better test coverage for it.
