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.
