Hello,
I had a customer pulling their hair out today because they couldn't 
login to their system. The error was consistently:
2013-06-07 08:42:44 MST postgres 10.1.11.67 27440 FATAL:  password
authentication failed for user "user
However the problem had nothing to do with password authentication. It 
was because the valuntil on the user had been set till a date in the 
past. Now technically if we just removed the word "password" from the 
error it would be accurate but it seems it would be better to say, 
"FATAL: the user "user" has expired".
Sincerely,
Joshua D. Drake
