Thread: PGDATA / data_directory
Hi,
My company is using PGDATA to store configuration files and the guc data_directory to give the path to the instance directory.
They would use it like this:
pg_ctl start -D <path to CONFDIR> -w
with this directory setup:
<somepath>/CONFDIR => postgresql.conf pg_hba.conf pg_ident.conf
<somepath>/SYSTEM => All the normal stuff in the postgres instance directory + recovery.conf recovery.done etc...
Is it commonly used ?
Thanks for your help / remarks / feedback.
Benoit.

That's the default cluster layout on Debian (and Debian-based distributions). /etc/postgresql/9.5/main/ /var/lib/postgresql/9.5/main/ /var/run/postgresql/9.5-main.pg_stat_tmp/ Christoph

Indeed. I never noticed data_directory was set in postgresql.conf file...
But then, why starting PostgreSQL with the following command ?
/usr/lib/postgresql/9.4/bin/postgres -D /var/lib/postgresql/9.4/main \
-c config_file=/etc/postgresql/9.4/main/postgresql.conf
It seems the following one work as expected and seems more logical with this
setup:
/usr/lib/postgresql/9.4/bin/postgres -D /etc/postgresql/9.4/main/

Digging in the (now git) history, it's been like that from the very beginning in 2005: https://anonscm.debian.org/cgit/pkg-postgresql/postgresql-common.git/commit/?id=9fa563e78366db3b27d680607c202b6fbb00bef2 It got touched a bit when 8.0 support was added, but basically not changed since then. https://anonscm.debian.org/cgit/pkg-postgresql/postgresql-common.git/commit/?id=fecbaad06c3683452228d31c0baffb01ba626a9a I'll see if I can simply remove it. Thanks for the suggestion. Christoph
