Tom Lane e92a88272e Modify hash_search() API to prevent future occurrences of the error ... spotted by Qingqing Zhou. The HASH_ENTER action now automatically fails with elog(ERROR) on out-of-memory --- which incidentally lets us eliminate duplicate error checks in quite a bunch of places. If you really need the old return-NULL-on-out-of-memory behavior, you can ask for HASH_ENTER_NULL. But there is now an Assert in that path checking that you aren't hoping to get that behavior in a palloc-based hash table. Along the way, remove the old HASH_FIND_SAVE/HASH_REMOVE_SAVED actions, which were not being used anywhere anymore, and were surely too ugly and unsafe to want to see revived again.		2005-05-29 04:23:07 +00:00
