I have installed PostgreSQL server 8.4 on my CentOS server sucessfully. After that, I login to CentOS server by using 'postgres' user, but I can not run any command, the error occur:
password authentication failed for user "postgres"
Here is some configurations in pg_hba.conf and postgresql.conf:
--------------------configuration in postgresql.conf-----------
listen_addresses = '*'
--------------------configuration in pg_hba.conf---------------
local all all md5
local all postgres md5
host all all 127.0.0.1/32 md5
host all all ::1/128 md5
