BUG #17469: postgresql-11.service file not configured to match setup/initdb options specified

The following bug has been logged on the website:

Bug reference: 17469
Logged by: Joe Hebert
Email address: jhebert(at)micron(dot)com
PostgreSQL version: 11.11
Operating system: RHEL 8.5
Description:

The following command was used to initialize the database (separate issue
with postgresql-11-setup not working):
/usr/pgsql-11/bin/initdb -A password -E utf8 -D /postgres/data/datafiles -X
/postgres/tranlog

Initialization completed successfully.

Then ran: sudo systemctl enable postgresql-11
Result: Created symlink
/etc/systemd/system/multi-user.target.wants/postgresql-11.service â
/usr/lib/systemd/system/postgresql-11.service.

Then ran: sudo systemctl start postgresql-11
Result:
Job for postgresql-11.service failed because the control process exited with
error code.
See "systemctl status postgresql-11.service" and "journalctl -xe" for
details.

Apr 27 16:19:40 systemd[1]: Starting PostgreSQL 11 database server...
Apr 27 16:19:40 systemd[1]: postgresql-11.service: Control process exited,
code=exited status=1

'exit-code'.
Apr 27 16:19:40 systemd[1]: Failed to start PostgreSQL 11 database
server.

After researching further, I reviewed file
/usr/lib/systemd/system/postgresql-11.service
and found the following offending line:
Environment=PGDATA=/var/lib/pgsql/11/data/

Which should have been set to /postgres/data/datafiles based in the option
provided to the initdb command.

Work-around: sudo systemctl edit --full postgresql-11
replaced the content, fixing the incorrect path
Result: PostgreSQL instance started successfully

If this is not considered a bug, please consider addressing this as an
enhancement. As a side note, I tried the "sudo systemctl edit" command
without the --full option to only override the one line, however, the issue
still persisted and required a wholesale replacement of the
postgresql-11.service file.
