You're gonna have to figure that one out yourself by using 2 models
and some clever trickery, or you might be able to dump the data and
import into postgres if it's generic enough with little effort but I
would much rather go the 2 model route even if it takes far more time.

Thanks lot for reply.
Few months ago i have studied about one gem which do this work, but i
forget the name.
Did any one know about this ?

http://en.wikibooks.org/wiki/Converting_MySQL_to_PostgreSQL describes
how to do a dump from mysql and restore to postgres but I don't see
any advantage of using a gem over that technique.

I really like yaml_db for this. I have only used it for SQLite to MySQL 
and MySQL to MySQL, but it works smoothly and quickly, and in my case, 
did not flinch at 2M records in a table.

I would like to add: if you have some custom mapping between the models,
you could write a simple rake task. Example:
