I am trying to migrate a postgresql database to mysql following this tutorial: http://mysqlworkbench.org/2012/11/how-to-migrate-postgresql-databases-to-mysql-using-the-mysql-wo
In my case I was using Windows 64bit and using "PostgreSQL ANSI(x64)" did connect to the Postgres database but it gave errors while migrating the database from Postgres to Mysql. I used the driver "PostgreSQL Unicode(x64)" and it worked. If your data contains unicode characters i.e. non ASCII characters use "PostgreSQL Unicode(x64)" drivers.
