MySQL has a nasty habit of ignoring standards; in every other database
I've used, if you want to quote an identifier (such as a field name),
you use ", not `.

The fields are also incompatable. int() is non-standard, for starters.

There are MySQL to PostgreSQL conversion tools out there that should
help.
