Kotresh,<br>
<br>
It looks to me like your pg_hba.conf is requiring a password for <br>
connections from 127.0.0.1, because this line:<br>
<br>
host all all 127.0.0.1/32 scram-sha-256<br>
<br>
Comes before this one:<br>
<br>
host all bucardo 0.0.0.0/0 trust<br>
<br>
If you want the "bucardo" user to connect with no password as that <br>
indicates, you should move that bucardo line before the "host" + "all" <br>
line, which takes priority the way you have it now.<br>
