I am using the official RPMs for RHEL-7 and am having difficulty in using a different database directory than the
default of
/var/lib/pgsql/9.6/data/
or
/var/lib/pgsql/10/data/
It is easy to modify the service file
/usr/lib/systemd/system/postgresql-9.6.service
with the line
Environment=PGDATA=/var/lib/pgsql/9.6/data/
to point to the location I want, but an RPM update will replace this file and break database startup.
I was hoping that there would be a line
EnvironmentFile=-/etc/sysconfig/pgsql/postgresql-9.6
or
EnvironmentFile=-/etc/sysconfig/pgsql/postgresql-10
to allow for customization of the environment variables, similar to the init.d startup, but I don't see one.
Am I missing something, or is the configuration of the systemd unit file an oversight?
Any information would be helpful.
Evan.
