Hi Rich Shepard,
Step 1-: Stop the postgres services and change the path of the data directory in postgres.conf file.
Step 2-: rsync the flie to new path. And start the service.
Step 3-: connect to postgres and check command output from psql shell SHOW data_directory; should see now data path.
I run Slackware (currently -14.2/x86_64) and postgres-11.5. The data
directory has always been located in /var/lib/pgsql/<version>/data. This
data directory is located in the / partition on a 240G SSD.
There's another 2T HDD with a /data partition and I want to both move the
current /var/lib/pgsql/data cluster to /data/pgsql/11 and have all future
databases use that location.
The PGDATA environment variable used to be used for this (but I never did
get it satisfactorily working). Web searches show changing initdb or,
perhaps, postgresql.conf (there is a /usr/share/postgresql.conf.sample but
no postgresql.conf).
As this is all new to me I want to learn how to:
1) Define a postgresl.conf and learn where it should be located.
2) Move all current databased in /var/lib/pgsql/11/data to /data/pgsql/11.
3) Create all new databases in /data/pgsql/11 by default.
I'm sure it's in the manual yet I'm unsure just where to start reading.
