Обсуждение: postgres+daemontools
I'm about to install postgres on a box that has daemontools on it and I would like to use it. Is there anybody here already running postgres from daemontools? Is it advisable? Do you have any problems or issues I should took care before trying it?
Thanks in advance.
We recently started using daemontools to manage the herd of postmasters (see
the recent thread regarding running multiple postmasters on a single
machine), and its working quite well.
We still have to figure out how to mimic the
"pg_ctl stop -m fast|immediate" modes,
svc -d /service/<server name> mimics "pg_ctl stop -m smart" which may be all
we need (I guess svc -i /service/<server name>; svc -d /service/<server
name>" effectively gives the "fast" mode.)

Is this multiple postmasters agains the SAME database? Or against multiple copies?

It's multiple postmaster's, each with its own $PGDATA folder and TCP port.

Is the data related to each other? How did you find open port numbers?

I didn't see daemon tools mentioned anywhere in these.

I find it much simpler to run multiple instances of postgres than using RH's init script. The run file I use is: #!/bin/sh exec 2>&1 exec setuidgid postgres /usr/local/pgsql/bin/postmaster -D /usr/local/pgsql/data
