Subject [jira] Commented: (JCR-889) Add bundle support for PostgreSQL
Date Tue, 19 Jun 2007 15:27:27 GMT

    [ https://issues.apache.org/jira/browse/JCR-889?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12506207

Alexander Klimetschek commented on JCR-889:

We have used that with Jackrabbit 1.3 and a PostgeSQL 8.2 and can confirm that it works, using
the PM for workspaces and versions.

As Postgres 8.2 has useful new features, we improved the implementation and schema for 8.2.
It has another index and the new 8.2 "RETURNING" feature, that allows to reduce the 2 statements
going through the index to 1.

The two changes are a different schema and a different PostgreSQLNameIndex class. The PostgreSQLPersistenceManager
class needs no changes.
