[Pgpool-general] some questions about pgpool

[Marcin]

1.When I set in pgpool options replication and authorizations by pam in 
pool_hba.conf, receives (in pg_hba.conf is 'trust'):

ERROR:  missing or erroneous pool_hba.conf file
HINT:  See pgpool log for details.

but log is empty (all logs options are on). When I change authorizations 
by 'trust' in pool.hba then works ok. Where is problem?

2.Why pgpool sending password only as plain text and doesn't operate md5 
or  ssl, this is very risk..?
