Hi,
thanks for the answer. But unfortunately i get this error when simply
trying to enter Postgres via PgAdmin.
So I've been away for a while, so what I have done today.
Configured postgresql to listen for 5433 port, and pgpool for 5432
(attached postgresql.conf and pgpool.conf)
and when trying to launch simple command such as:
postg...@testlab /DB/bin $ ./createdb -p 5432 test
i get the following
2009-07-16 15:45:56 LOG: pid 4076: pgpool successfully started

and system just hangs .. waits for smthn and no further information
until i stop pgpool.

i configured pgpool without much of a problem, and replication works

Possible last query was: "SET DateStyle=ISO;SELECT oid,
pg_encoding_to_char(encoding) AS encoding, datlastsysoid
FROM pg_database WHERE oid = 24629" kind details are: 0[C] 1[D]
maybe anyone has any ideas?
Both servers have freshly installed Gentoo Linux on them with
Postgresql-8.3.4 and pgpool-II-2.2.2
There are 2 possible reasons:
- Multi statement(mulitple SQL statements conjuncted with ";") does
not work with pgpool-II.
- Queries relying on OID does not work with pgpool-II.
I thought these are stated in the doc as limitations of pgpool-II.
