Обсуждение: pgsql: Fix assign_record_type_typmod().
Fix assign_record_type_typmod(). If an error occurred in the wrong place, it was possible to leave an unintialized entry in the hash table, leading to a crash. Fixed. Also, be more careful about the order of operations so that an allocation error doesn't leak memory in CacheMemoryContext or unnecessarily advance NextRecordTypmod. Backpatch through version 11. Earlier versions (prior to 35ea75632a5) do not exhibit the problem, because an uninitialized hash entry contains a valid empty list.
