No one in mine.
There are still some bad things, but they are old:
1. elog(NOTICE) in lock manager when locking was not succeeded. Hope that our recent changes will reduce possibility
ofthis.

I tried to fix this before 6.4 but without success (don't
remember why).

Seems to me that elog(FATAL) should call siglongjmp(Warn_restart, 1),
like elog(ERROR), but force exit in tcop main loop after
AbortCurrentTransaction(). AbortTransaction() does pretty nice
things like RelationPurgeLocalRelation(false) and DestroyNoNameRels()...
