+PostgreSQL is an advanced object-relational database management
+system (ORDBMS) based on POSTGRES. With more than 15 years of
+development history, it is quickly becoming the de facto
+database for enterprise level open source solutions.
+
+Before you can run postgresql you'll need to create the database;
+please see README.SBo.
+
+You need a "postgres" user and group prior to building postgresql.
+Something like this will suffice for most systems:
+  groupadd -g 209 postgres
+  useradd -u 209 -g 209 -d /var/lib/pgsql postgres
+Feel free to use a different uid and gid if desired, but 209 is
+recommended to avoid conflicts with other stuff from SlackBuilds.org.

+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/data --locale=en_US.UTF-8 -A md5 -W"
+
+Additionally, a logrotation script and init script are included.
+For production level log file handling please read
+https://www.postgresql.org/docs/14/logfile-maintenance.html
+
+In order to start postgresql at boot and stop it properly at shutdown,
+make sure rc.postgresql is executable and add the following lines to
+the following files:
+
+	/etc/rc.d/rc.local
+	==================
+	# Startup postgresql
+	if [ -x /etc/rc.d/rc.postgresql ]; then
+		/etc/rc.d/rc.postgresql start
+	fi
+
+	/etc/rc.d/rc.local_shutdown
+	===========================
+	# Stop postgres
+	if [ -x /etc/rc.d/rc.postgresql ]; then
+		/etc/rc.d/rc.postgresql stop
+	fi
+
+Additionally, rc.postgresql script has additional modes for stop/restart:
+  force-stop|force-restart (i.e. pg_ctl 'fast' mode)
+  unclean-stop|unclean-restart (i.e. pg_ctl 'immediate' mode)
+See https://www.postgresql.org/docs/14/app-pg-ctl.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 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
+
+This script builds postgresql with some useful extension modules from
+the contrib directory, see PG_EXTENSIONS in SlackBuild file.
+To build PostgreSQL with all extensions, use the following command:
+
+	# PG_EXTENSIONS=ALL ./postgresql.SlackBuild
+
+Please note that in order to actually use extension, you must execute
+'CREATE EXTENSION [ IF NOT EXISTS ] extension_name' for each extension.
