Обсуждение: pgsql: Fix exception safety bug in typcache.c.
Fix exception safety bug in typcache.c. If an out-of-memory error was thrown at an unfortunate time, ensure_record_cache_typmod_slot_exists() could leak memory and leave behind a global state that produced an infinite loop on the next call. Fix by merging RecordCacheArray and RecordIdentifierArray into a single array. With only one allocation or re-allocation, there is no intermediate state. Back-patch to all supported releases.
