Also, the dynamic pg_hba changes work only for new connections that are
being established via jdbc. Existing connections seem to able to make
connections.

You do know you can change pg_hba.conf without a restart?

As for the drop going into a wait state, you might want to look around

should not block for longer than whatever is your longest transaction
touching that table.
