Moving from PostgreSQL to MySQL

I have found a forum on the MySQL site (something like this on the net is as scarce as chicken teeth :-D ) that talks about converting a PostgreSQL db to a MySQL one (well I still need to try it out, will let everyone know): http://forums.mysql.com/read.php?83,34517,34517#msg-34517 Why? Well if you want the new XWiki to work and you don't mind the kind of DB to use, then this is a good solution. But I wanna try something. I want to copy my PSQL db to MySQL and get that to work on the new XWiki and hopefully I can convert it back to PSQL and it'll work on the new XWiki (HOPEFULLY)!!! On that forum thread, there is a plugin for SQuirreL SQL that basically allows you to copy between DBs! Now thats handy! I want to test that out and see if it will work! Oh how I hope it'll work!!!
