Description

since the lock is not released before reporting errors, it will leads to panic during transaction abort since the lock will be acquired again. A RWLock is acquired twice in one process will leads to panic.

There are two occurrences of this bug in this function, one for AO, one for parquet.

			if (id == NEXT_END_OF_LIST)
			{
				pfree(allfsinfoParquet);

				ereport(ERROR, (errmsg("cannot open more than %d "
				      "append-only table segment "
				      "files cocurrently",
				      MaxAORelSegFileStatus)));

				return false;
			}
