Commit c66a7d75e652 modified DROP DATABASE so that if interrupted, the database is known to be in an invalid state and can only be dropped. This is done by setting a flag using an in-place update, so that it's not lost in case of rollback. For databases with many ACLs, this may however fail like this: ERROR: wrong tuple length This happens because with many ACLs, the pg_database.datacl attribute gets TOASTed. The dropdb() code reads the tuple from the syscache, which means it's detoasted. But the in-place update expects the tuple length to match the on-disk tuple. Fixed by reading the tuple from the catalog directly, not from syscache. Report and fix by Ayush Tiwari. Backpatch to 12. The DROP DATABASE fix was backpatched to 11, but 11 is EOL at this point.
