PostgreSQL data comparsion tool

I am looking for a tool/command which can compare data between two PostgreSQL databases. The reason to do this is to have some external verification that the SQL script responsible for data migration from one PostgreSQL database to the other have been written correctly.开发者_运维百科

Any pointers would be appreciated regards Sameer

EMS makes a tool which can do this.

The PostgreSQL site has a nice Software catalogue. Peruse the Administration/development tools category.
