Enclosed is xwiki-postgresql-1.0-beta-1.sql , the equivalent of xwiki-mysql-1.0-beta-1.sql (available on the XWiki download area) for Postgres.
This provides an empty Postgres database as a starting point for working with XWiki 1.0Beta.
It has been tested with PostgreSQL 8.2.1 and XWiki 1.0B3.
Please test and provide feedback.
