Ok, I looked and there was a table pg_user. I notice it is in the template and
my database. I modified it using the command (in psql)
ALTER USER doug with PASSWORD FRED;
This seems to have worked and the command returned ALTER USER.
Ok I removed the file name in the pg_hba.conf file and restarted postgres.
I get the same message when I try to connect from Java on the PC! :(
As a test, I tried this command from the linux shell
psql -u -h localhost doug
Everything seems to work fine.
I also tried the same command with a bogus password and it also worked! so the
above statement must not be checking passwords or something.
I am totally lost on what to do.
