[Pgpool-general] Pgpool-II - replication problems

[nir osovsky]

Thank you, Jaume.

Attached my pg_hba.conf (identical in 2 servers) and pgpool.conf.  I
appreciate if you can let me know if I need to change something.

pg_hba.conf
=========
# "local" is for Unix domain socket connections only
local   all         all                               trust
# IPv4 local connections:
host    all         all         127.0.0.1/32          trust
host    all         all         192.168.158.38/32         trust
host    all         all         192.168.158.39/32         trust
# IPv6 local connections:
host    all         all         ::1/128               trust
