Hi, I looked at this patch today. I went through all the calls switched to equalRowTypes, and AFAIK all of them are correct - all the places switched to equalRowTypes() only need the weaker checks.
There's only two places still calling equalTupleDescs() - relcache certainly needs that, and so does the assert in execReplication(). As for attndims, I agree equalRowTypes() should not check that. We're not really checking that anywhere, it'd be quite weird to start with it here. Especially if the plan is to remove it entirely. regards -- Tomas Vondra EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
