Upgrade to OpenACS 5.8
OpenACS (5.8) works with PostgreSQL 9.1 or newer out of the box, no special configurations in postgresql.conf are needed like with previous versions.
To work with PostgreSQL 9, one has to use an actual postgres driver:
- AOLserver 4.5.* + nspostgres (tag: nspostgres_v4_r2)
- NaviServer 4.99.5 (or newer) + nsdbpg
OpenACS core + commonly used packages (search, forums, xowiki, ...) have been tested with PostgreSQL 9.2.4
For new installs, OpenACS 5.8 works without further considerations. When upgrading the database to PostgreSQL 9.*, one has to keep in mind, that not only the sql-install scripts have to be SQL 9.* compatible, but as well the update scripts (migration scripts). During the work for making OpenACS compatible with PostgreSQL 9.*, we did not update (all) of the migration scripts (e.g. kernel upgrades) of earlier versions, therefore one should run the upgrade scripts to OpenACS 5.7 with an PostgresSQL 8.* database.
Therefore, the following upgrade steps are recommended for upgrading from OpenACS 5.5 to 5.7 to OpenACS 5.8:
- For users of PostgreSQL versions earlier than 8.4: In case you run a version of OpenACS earlier than 5.5 then upgrade first your code to OpenACS 5.5 (oacs-5-5 branch from the CVS Repository), then dump your database and reload it into PostgreSQL 8.4 (e.g. into PostgreSQL 8.4.22, the end-of-life of which was in July 2014). Then continue with the next step below.
- For users of PostgreSQL version 8.4 (or newer before 9): Make sure, you are running Tcl 8.5, then get OpenACS 5.8 (not 5.9) and upgrade OpenACS and your used packages (e.g. via acs-admin/apm + "install packages"). Then dump the database and restore it in PostgreSQL 9.*.
