I've updated Jeff Janes' test suite to support testing of exclusion constraints that are equivalent to unique indexes: https://github.com/petergeoghegan/jjanes_upsert/commit/a941f423e9500b847b1a9d1805ba52cb11db0ae9 (This requires a quick hack to the Postgres source code to accept exclusion constraints as ON CONFLICT UPDATE arbiters). So far, everything seems okay with exclusion constraints, as far as I can determine using the stress tests that we have. This is an encouraging sign. -- Peter Geoghegan -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
