[xwiki-users] What is recommended DB for XWiki?

Hello, As we are currently migrating our XWiki server to 64bit platform I believe I have freedom to consider switching DB. We are currently using 32bit MySQLv5.0.77 (innodb engine, 500M of attachments stored in-db) so the options are · Upgrade to MySQLv5.6.x · Migrate to PostgreSQL 8.1 (via XWiki export/import as xar backup feature) The question is: which of those databases is more supported? (mostly used for development, supported by admin application, etc) Regards, Roman
