It is not clean what database you need to reconnect automatically
after the dropping. Moreover you may not have permissions to connect
other databases.
That's a fair point, so perhaps DROP DATABASE should still fail if the
current connection is to that database (preferably with a helpful error like "you cannot drop the database you are connected to"). There should be an easy way to close all
other connections to it, though.
2) The workaround requires superuser privileges, which I don't think should
be required to drop your own database.
It does not require it. You might also be an owner to drop the database.
It does when I try it:
SELECT pg_terminate_backend(procpid)
FROM pg_stat_activity
WHERE datname = 'dropme';
ERROR: must be superuser to signal other server processes In this case the user was the owner of "dropme", but another user was also connected to it. I believe that should not stop the owner from dropping their database.
