Apparently something has changed -- the question is what? If nothing
on the server, what about on the user's machine? When was the last
time it was known for certain to have worked?

What method were you using before you changed it to "trust"? If
you change it back, can you log in as the user from someplace that
works for other users? Can the user in question log in as any other
user from wherever his or her own account is failing? What error
shows up in the server's logs?

Are you restricting logins by IP address? If so, has the user's
IP address changed?

It might be useful to see the contents of pg_hba.conf.
