- add stored procedure sec_session_property__upsert to address concurrency problems with updates in sec_session_properties; implementation for PostgreSQL and Oracle are added, latter is not tested. - bump version number to 5.9.0d4
bootstrapper can now load either the Oracle or PostgreSQL acs-kernel datamodel. It checks on-the-fly for which db is configured in the OpenNSD database pools allocated to OpenACS. Only acs-kernel is correctly self- configured at this point.
