PostgreSQL schema compatibility

Trying to install the most recent trackfield.module (6.x-1.x-dev from 2009-Nov-17) under PostgreSQL-based Drupal 6.14 installation gives an error complaining about an invalid SQL syntax.

Because I've dealt with a similar issues before when trying to use other modules, so choose to take a radical path and rewrote the .install file using the Schema API, which, in theory, should be the most RDBMS-agnostic way to deal with SQL DDL.

Now installation goes well under PG. Also, I've tried saving/editing an item that uses trackfield with success. So I suppose, this is a way to go.

Sorry, for not providing a patch, just a whole file.
