It'd be nice to have some more-automated way of doing this type of correction. Ordinary scripting doesn't look very promising, because I don't see an easy way to deal with the need to connect to every database in the cluster; that seems to depend on a lot of local characteristics about usernames and authentication. Maybe it'd be worth building some sort of infrastructure that would allow this to be done at a lower level. It's not hard to imagine an autovacuum-like or bgworker-based thingy that could run around and apply a given SQL script in every database, bypassing the usual worries about authentication and connections-disabled databases. That seems like a lot of work for a need that only comes up once in awhile, but perhaps it'd have more applications than just catalog corrections. regards, tom lane
