I'm playing around pgpool2.
I'm connecting to postgresql which is running on port 5432 with command psql -U postgres -p 5432 and it's connecting normally.
When I'm connecting to pgpool2 running on 9999 port with command psql -U postgres -p 9999 - it returns back dialog like: psql: root@master:/linux/path#
What I'm doing wrong? Is there way to connect to pgpool using psql? I cannot connect to it from application also.
UPD I've got following error pool_do_auth: maybe protocol version mismatch (current version 3)
Solved : Problem was in pgpool auth on backends. Editing pg_hba.conf fixed problem.
This error message and behavior are because of a problem with pgpool authenticating to postgres, not with you authenticating to pgpool as you might suspect. If you check the postgres logs, it will tell you which line in your postgres pg_hba.conf is being rejected.
However, since (IIRC) pgpool cannot do peer authentication, it is probably this one, which says that all local (unix socket) connections will be authenticated by pretending the system username is the postgres username:
local all all peer
You want to change that to:
local all all trust
At least to make things work. However, you will lose some security this way. However, if all your users (that can access the unix socket) are trusted, this is okayish.
