I don't know how complex your schema is, but I would create the objects
manually and then use Perl scripts to copy the data. Copying shouldn't
be a problem because MySQL supports things like this:

SELECT *
INTO OUTFILE '/tmp/emp.csv'
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\n'
FROM emp

That should be picked up quite nicely by the COPY command from PostgreSQL.
