Before you can run postgresql you'll need to create the
database files in /var/lib/pgsql. The following should do
the trick.
# su postgres -c "initdb -D /var/lib/pgsql/14.1/data --locale=en_US.UTF-8 -A md5 -W"
# su postgres -c "initdb -D /var/lib/pgsql/14/data --locale=en_US.UTF-8 -A md5 -W"
Additionally, a logrotation script and init script are included.

From PostgreSQL 9.6 we support in place database upgrades using pg_upgrade:
http://www.postgresql.org/docs/14/pgupgrade.html
From PostgreSQL 9.3 we support in place database upgrades using pg_upgrade:
https://www.postgresql.org/docs/14/pgupgrade.html
A few hints for PostgreSQL 9.6 -> X.Y upgrade:
- Don't remove old PostgreSQL 9.6.x package
- Install PostgreSQL X.Y, note that binaries are in
'/usr/lib64/postgresql/X.Y/bin'
A few hints for PostgreSQL 10.x -> 14.x upgrade:
- Don't remove old PostgreSQL 10.x package
- Install PostgreSQL 14.x, note that binaries are in
'/usr/lib64/postgresql/14/bin'
- Follow regular pg_upgrade docs
- Remove old package when transition is over, or read comments in
rc.postgresql if you want to run multiple PostgreSQL versions in parallel
- Check the /usr/bin for stale symlinks for old binaries_
e.g. in v10.0 pg_xlogdump got renamed to pg_waldump.
This script builds postgresql with some useful extension modules from
the contrib directory, see PG_EXTENSIONS in SlackBuild file.
