Hi, last week we've installed XWiki running on Tomcat with Postgres. There were some changes necessary with the database layout for Postgres, therefore I wanted to submit the changes we did. --------- changes-xwiki-postgres.sql /* This SQL-file consists some changes necessary to use XWiki together * with PostgreSQL. The changes are tested. They have to be applied * during installation, otherwise XWiki won't work. */ /* Copied from http://www.xwiki.org/xwiki/bin/view/Dev/PostgresDatabase * Thanks Artem. */ ALTER TABLE xwikiclassesprop ALTER xwp_unmodifiable TYPE boolean USING xwp_unmodifiable=1; ALTER TABLE xwikidblistclasses ALTER XWL_MULTISELECT TYPE boolean USING XWL_MULTISELECT=1; ALTER TABLE xwikidblistclasses ALTER XWL_RELATIONAL TYPE boolean USING XWL_RELATIONAL=1; ALTER TABLE xwikislistclasses ALTER XWL_MULTISELECT TYPE boolean USING XWL_MULTISELECT=1; ALTER TABLE xwikislistclasses ALTER XWL_RELATIONAL TYPE boolean USING XWL_RELATIONAL=1; /* Changed after errors during file upload were discovered: * xwikiattachment_archive.xwa_archive: type text --> type bytea * xwikiattachment_content.xwa_content: type text --> type bytea * * Altering the data type at once is not possible, Postgres * can't cast from text to bytea. This error is even reported * if the table is empty. */ ALTER TABLE xwikiattachment_archive DROP COLUMN xwa_archive; ALTER TABLE xwikiattachment_archive ADD COLUMN xwa_archive bytea; ALTER TABLE xwikiattachment_content DROP COLUMN xwa_content; ALTER TABLE xwikiattachment_content ADD COLUMN xwa_content bytea; --------- HTH Best regards, Fabian.
