that can be done, but plain-text passwords are not good. also, it doesn't
stop users from cruising other databases for unprotected data.
my patch will control that, at least in the context of apach/php/libpq.

most of the databases have one user, that of the httpd process.
from what i've seen, this is fairly standard with virtual hosting.
until we have per-database users, generally what you end up doing is creating
a per-database user/password table, and then write applications that control
things based on that table, as opposed to the system table. this means that
all of the tables in a database need to be read/write by one central user.
i've always found this hokey, but necessary.
the up-coming per-table userlist will help this alot.
