Hi. I'm surprised, I thought ACLs would never be empty for a database. Does that mean nobody can connect to this database? I guess SUPERUSER and/or its datDBA can? What does a NULL AclItem[] mean exactly? (BTW, datallowconn is true)
Thanks, --DD ddb=> select datname, datdba::regrole::text from pg_database where datacl is null; datname | datdba ---------+-------- qadb | qauser (1 row) PS: Was also surprised with #42883: ERROR: no binary output function available for type aclitem Thankfully datacl::text[] works fine in binary mode.
