Change elog(ERROR) to Assert(false) for two reasons: (1) "unrecognized hash action code" could hardly really happen; (2) even if it could happen, elog(ERROR) won't save us since in many places we have to check the return code of hash_search() and decide the error level.
On a separate matter, can anyone please explain me how this piece of code works: /* no free elements. allocate another chunk of buckets */ if (!element_alloc(hashp, HASHELEMENT_ALLOC_INCR)) return NULL; /* out of memory */ element_alloc() in fact uses MemoryContextAlloc() stuff. So if element_alloc() fails, it actually elog(ERROR) itself and jump out of our control, and we could never get a chance to check its returned value. So many places like this: if (!hash_search(... HASH_ENTER ...)) elog( ...) could never happen?
