Quick question MySQL --> PgSQL

Folks,
Just a quick question ... I need to do a regular transfer (daily + on
demand) of data from a MySQL database to a PostgreSQL database and back
again.  Can anybody steer me towards a good script for this, or do I
have to write my own in PHP?
Sorry to bother everyone with something that isn't strictly a SQL
question, but I'm not sure where else to ask.

available.
