What about the following situation:

    - 3 databases: 'devel', 'staging', and 'production'

    - one user, 'httpd', which needs access to all 3 databases but
      doesn't own any of them

    - I create the 'httpd' user when I'm connected to, say, template1

    - I issue a command that changes the httpd user in some way (e.g.
    drops the user, alters the user, etc.) -- what happens?

Also, what happens if I enable the GUC var, create a bunch of different
users/databases, and then disable it again?
