## Install PostgreSQL

OpenACS docs are written by the named authors, and may be edited by OpenACS documentation staff.

Skip this section if you will run only Oracle.

OpenACS 5.9.0 will run with PostgreSQL 9.0 or newer. 9.5 is currently the recommended version of PostgreSQL.

It is recommend to use a prepackaged version of PostgreSQL, which are available in source and binary formats from www.postgresql.org/download/.

Larger installations might want to tune the PostgreSQL installation with e.g. the utility pgtune, which is also available via `apt-get install pgtune` or `dnf install pgtune` on Debian/Ubuntu or RedHat systems.
