Is this the correct syntax for starting Postgres using a separate config_file for each host? We like to take advantage of the Unix variable “hostname” to source in the name of the file.
Machine1: (notice we are using the `hostname` unix variable)
pg_ctl start -D /hostname/postgres/data -l /hostname/postgres/log -o config_file="/nfs/global/postgres-`hostname`.cnf"
Machine2: (notice we are using the `hostname` unix variable)
pg_ctl start -D /hostname/postgres/data -l /hostname/postgres/log -o config_file="/nfs/global/postgres-`hostname`.cnf"

Hi David,
Which command? Can you give me an example?
Say, I want to put the config file on a share drive so all my postgres configuration file can be seen in one location.
/nfs/global/postgres-<hostname>.cnf
Example:
/nfs/global/postgres-machine1.cnf
/nfs/global/postgres-machine2.cnf
/nfs/global/postgres-machine3.cnf

That would be incorrect, you just need to change server startup commands.
