Hi everybody! I need some help please.
I was using as a test pgpool-II 2.3.2.2 compiled from ports on FreeBSD
8.1-RELEASE with PostgreSQL 8.4.4_2 for Synchronous Multi-Master
Replication.
Everything was working fine. I've upgraded to PostgreSQL 9.0.1_2
and pgpool-II 3.0.1 (same server but kernel upgraded to patchset 2 which
I believe is not relevant anyway but just for the record) and I get this
incredible error:

I've tried to rename the config file and to create a directory with the
same config file name (as it seems to be expecting but just for a try,
because it's clearly insane) but it doesn't fix it. In fact the error
pool_init_pool_passwd: couldn't
open /usr/local/etc/pgpool.conf/pool_passwd. reason: Not a directory
2010-12-15 17:56:58 DEBUG: pid 4876: shmem_exit(0)

directory
2010-12-15 17:56:58 DEBUG: pid 4876: shmem_exit(0)
I'm pretty sure this is a little and very easily fixable bug.
I've sent a private email to the FreeBSD port maintainer too that is
most likely to be in this mailing list anyway, but just to be sure.
