Convert rt DB from MySql -> PostgreSQL

RT Users

I’d like to convert my MySQL backed RT to PostgreSQL in the interest
of standardizing on 1 opensource DB within our department (we also have
Oracle, MSSQL, Access, & FoxPro Applications floating all over the place).

Has anyone done this? Any tools/tips?

Setup:
FreeBSD: 4.8, RT: 3.0.7, MySQL: 4.0.16, Postgres: 7.3.4, Apache+ssl:
1.3.28, Perl 5.8.1, mod_perl-1.28 all installed from ports.

Thanks,
Mike
