Re: Does the initial postgres user have a password?

Other tools may try to connect with different users or with same users but
using ip (not local host) and pg_hba.conf file may not allow paswordless
login except localhost.Reseting postgres password with alter user, and
configuring pg_hba.conf file can solve your problem.
