Devart dbForge Data Compare for PostgreSQL allows you to compare data of databases.

If you want to change default comparison settings, go to the Options and Mapping tabs of the New Data Comparison wizard.
Select the data to synchronize in the grid with comparison results. (To do this, select check boxes next to tables (or views) in the top grid. You may also select check boxes next to individual records on the Only in Source, Only in Target, and Different Records tabs of the bottom grid).
Click the Synchronize button on the Comparison toolbar to open the Data Synchronization wizard.
Select where to output the synchronization script in the wizard and then click the Synchronize button.
