Re: serializable transaction: exclude constraint violation (backed byGIST index) instead of ssi conflict - Mailing list pgsql-hackers

I believe we are after multiple issues/improvements:

1. Could we extend https://git.postgresql.org/gitweb/?p=postgresql.git;a=commit;h=fcff8a575198478023ada8a48e13b50f70054766 by adding support for exclude constraints?

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.
