I thought about that approach, but it seemed better to make sure that things didn't get broken at any isolation level by patches dealing with DROP INDEX CONCURRENTLY. If you're sure that could never happen, we could save a few dozen lines of isolation test code. It's not like READ COMMITTED will never get tested -- I would bet that upwards of 99% of the make installcheck-world runs or make installcheck -C src/test/isolation runs are at that isolation level. -- Kevin Grittner EDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

Hm, given what we're trying to test here, wouldn't it be better to explicitly use READ COMMITTED?
