Fast Data Comparison with PostgreSQL returns with error 42883: operator doesn't exist

Entered on behalf of Michele.I used the Fast comparison during the first attempt, it was indeed considerably faster (and it returned a Message 42883: operator doesn't exist - are the errors Postgres errors or do you have a specific meaning in DBCS?).

Does that mean that we don't *need* to do a "regular" comparison to get accurate results, that Fast Compare is just as accurate and that the only difference between the two is about where it does the actual work?

We did not find such errors during testing this new feature. Would you post the structures of the compared tables and comparison settings?

This approach gives us quite an accurate result , but collisions are possible. We recommend to use "regular" comparison in order to get a result with 100% accuracy.
