Subject: 5 Instances in one box -- Postgresql.conf Archive Log command
Date: Mon, 9 Feb 2026 09:35:06 +0000
Message-ID: <76ab7592d45d47898d1a8e7bf0edd5ad@alte-leipziger.de> (raw)
Hello,
We have 5 instances running under different ports and we have multiple servers with the same structure. i.e. I have multiple servers with the same five instances per server configuration.
/var/lib/pgsql/INST1/data - Port number 1234
/var/lib/pgsql/INST2/data - Port number 1235
/var/lib/pgsql/INST3/data - Port number 1236
/var/lib/pgsql/INST4/data - Port number 1237
/var/lib/pgsql/INST5/data - Port number 1238
I try to make changes to postgresql.conf in our sandbox/testing server for just one instance and I simply copy over the changes to all the instances and then to all the servers.
I want to place the archived WALs in separate directories for each instance. How can I introduce the INST1 INST2 INST3 INST4 names in the archive command variable /mnt/server/archivedir , without explicitly editing changing each postgresql.conf file? It is not absolutely important for me that the archive log directories bear the exact names INST1 2 3 ..5. however, I want the archive log directories to be resolved to unique names based on which instance the archive is done.
Thank you in advance for your time.
LG
Ram
archive_command = 'test ! -f /mnt/server/archivedir/%f && cp %p /mnt/server/archivedir/%f' # Unix
