I believe we are after multiple issues/improvements:

2. Fully support gist & constraints in serializable transactions. I did not yet test a unique constraint backed by a gist constraint, which is also interesting to test I assume. This test would tell us if there currently is a status quo between btree and gist indexes.

Regarding the remark in (2), I forgot that a unique constraint cannot be backed by a gist index, so forget the test I mentioned.
