I wonder whether we should allow a standalone backend (postgres) to connect regardless of datallowconn. The tradeoff is that you could break your template0 slightly more easily, but you can break template0 anyway if you are determined. If you have actually done that :-(, my recommendation would be to build a modified backend with the check in src/backend/utils/init/postinit.c diked out ... regards, tom lane
