Another question for PostgreSQL users

Anyone out there using the PostgreSQL for WordPress plugin(PG4WP)? Specifically, are there any issues with the latest WordPress 3.3.1? Unfortunately, I haven’t been able to get hold of the developer, so I would really appreciate a response from a user.

Also, when I upgraded from 2.9 to 3.2.1, I started having problems with tags. They get really messed up with previous post’s tags. If anyone else has this problem and knows how to fix it please let me know.

I’d really like to move to a mysql database, but transferring from postgresql looks like a very difficult process.
