Hi, Oliver,
I follow your instructions to do on my local machine, edit the file
pg_hba.conf:
local all password
host all 127.0.0.1 255.255.255.255 crypt
then I connect with psql, use the -u option, I got the following errors:
% psql -u
Username: postgres
Password:
User authentication failed
Connection to database 'postgres' failed.
User authentication failed
If I don't edit the file pg_hba.conf, I can connect template1
with no problem. I have run createuser and have created the user 'postgres'.
Would you like to tell me how to solve this problem, thanks.
-Kevin.
