Alternate Datafile Location

Howdy,

Here's our filesystems:

[postgres(at)xxx data]$ df -h
Filesystem Size Used Avail Use% Mounted on
devtmpfs 80G 0 80G 0% /dev
tmpfs 80G 44M 80G 1% /dev/shm
tmpfs 80G 716K 80G 1% /run
tmpfs 80G 0 80G 0% /sys/fs/cgroup
/dev/mapper/rhel-root 28G 4.5G 23G 17% /
tmpfs 80G 8.0K 80G 1% /tmp
/dev/sda2 1014M 457M 558M 46% /boot
/dev/sda1 599M 5.9M 594M 1% /boot/efi
/dev/mapper/pgwalvg-pgwalvol 570G 28K 541G 1% /PG_WAL
/dev/mapper/pgdatavg-pgdatavol 2.3T 28K 2.2T 1% /PGDATA
tmpfs 16G 0 16G 0% /run/user/1242651222
tmpfs 16G 0 16G 0% /run/user/1271246868
[postgres(at)xxx data]$

Our Postgres software install and data directory is on root:

[postgres(at)xxx data]$ pwd
/var/lib/pgsql/16/data
[postgres(at)thiludbapql01 data]$ df -h .
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/rhel-root 28G 4.5G 23G 17% /
[postgres(at)xxx data]$

We want our database datafile storage to be on /PGDATA. I don't see
anything in the version 16 documentation on how to accomplish this. I must
be missing it somewhere. Could someone please advise?

Thanks,

Sam
