If you can convert the database schema, then in mysql do a dump of the
tables like this:
select * from table into outfile '/tmp/filename';
(see http://dev.mysql.com/doc/refman/4.1/en/select.html)
and then import it into postgres like this:
\copy table from '/tmp/filename'
(see http://www.postgresql.org/docs/8.2/interactive/sql-copy.html)
That's much better because it creates a CSV like file which postgres can
process in one go.
Using complete inserts to do a conversion is horribly slow because
postgres does a single transaction per insert - so you can either wrap a
number of inserts inside a transaction, or do a copy like this (copy is
best).
