[pgpool-general: 938] Re: Issue w/ md5 auth in master/slave mode

[Michael Barrett]

Yes - I just did a diff of the two files and they are exactly the same.

I made sure (just now) to restart both postgres servers just in case.

Here's the output I'm getting from pgpool in debug mode when I try to make the connection (with sslmode=allow):

And then psql's output:

ubuntu at app1:~$ psql "host=localhost port=9999 user=mike sslmode=allow"
psql: ERROR:  MD5 authentication is unsupported in replication, master-slave and parallel modes.
HINT:  check pg_hba.conf
ERROR:  MD5 authentication is unsupported in replication, master-slave and parallel modes.
HINT:  check pg_hba.conf


Thanks again for your help!
