This project needs more testing and feedback, though. Use it at your own risk!
Most of the information holds good, as given by Original Author. Important updates are addition of a python script to fix minor issues with sql conversion and, a shell script which does all the job for us. You essentially, need to use only the "migrate.sh" script. The syntax is as follows.
migrate.sh <postgresql-db-name> [mysql-db-engine]mysql-db-engine is optional and, it defaults to MyISAM
This utility takes dump of the postgresql database using pg_dump command before converting it to mysql.
