What's there to say? Just start chugging away. Do some research when you hit a wall.

The biggest gotcha will almost certainly be the lack of any upsert support in PostgreSQL. If you can live without upserts, you'll never look back, IMO..

MySQL has a much better GUI based query browser than anything I've seen in the postgres world. Postgres has a very good command line query tool though.

But yeah, no upserts.

Go to your ORMs configuration and change 'mysql' to 'pgsql' ;)
