Aha! Thank you, that was the secret. I do not believe that these
environment variables are documented in 6.3.1 either -- at least, I didn't
find them. I tried USER, but not PGUSER. Setting PGUSER worked.

This is how the Pg.pm perl connectdb function works; that _is_ documented
in the Pg man page. Presumably this is a "documented" feature of libpq,
but the documentation hasn't caught up yet. (Of course, it's always scary
to assume things like that.)
Thanks again for your help.
