Hackers, I'm seeing from reports on IRC that 8.3 may cause an unprecedented number of upgrade issues for users who have old, badly-written applications. Stefan K, for example, was reporting the necessity of re-writing 3000 lines of his PL/pgSQL code on an older app (about 10%).
While we are right to choke down abuse of implicit casting, it might be a good idea to give users stronger warnings and instructions. I'm thinking that we need to warn everyone about: 1) They need to use 8.3's pg_dump, not the old version, to upgrade (this is always true but now doing it wrong will break a lot more users). 2) They need to check for bugs 3) If Robert gets his type-cast backport package together, the location of that. I'm thinking this warning should go (prominently) into the release notes, the community notice, and the extended web release. -- --Josh Josh Berkus PostgreSQL @ Sun San Francisco ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
