Hey, if people want it back, it is easy to do.

My only goal was to make psql consistent with other applications that
require passwords.

What about 'ps -e' that shows all environment variables?  This is in
some ways worse than piping the password into psql.  At least there was
some chance that they were using 'cat' from a file with the proper
permissions.  WIth PGPASSWORD, there is no way to restrict who can see
it via 'ps -e'.

Seems we shouldn't allow PGPASSWORD either.

The idea of allowing the password to be stored in a file with 600
permissions seems quite standard.  CVS does this.
