Subject: pgsql: Reject invalid databases in pg_get_database_ddl()
Date: Fri, 17 Apr 2026 04:21:56 +0000
Message-ID: <E1wDaiK-001M3A-0W@gemulon.postgresql.org> (raw)
Reject invalid databases in pg_get_database_ddl()
An invalid database has datconnlimit set to -2. pg_get_database_ddl()
emits this verbatim as CONNECTION LIMIT = -2, which ALTER DATABASE
rejects. Error out early instead.
