Huh? \c is checked exactly as tightly as a fresh connection --- it
*is* a fresh connection, as far as the server is concerned.

See "sameuser" option in pg_hba.conf.

The above line does not allow connections to ANY database other than
bobsdb. If anyone can connect to anything else at all, it's because
you have additional pg_hba lines that you're not showing us.

> hostssl bobsdb a.b.c.d 255.255.255.255 ident sameuser

"sameuser" in the database column (column 2) was what I was talking
about. "sameuser" as an ident argument is a different concept
altogether.
