CA PAM says that there is no support for PostgreSQL - Data generation. I was able to create generation rules and preview data. When published the data to target, got the following error:

Publish errors occurred - See below
No tables to publish - STOPPING
As per the documentation (link given below), PostgreSQL is not a supported Databse for generation.
Supported Data Sources - CA Test Data Manager - 4.5 - CA Technologies Documentation
The reason that you were able to make a connection to it and create rules is to do with the fact that
"As long as you have a valid driver for any Database, Datamaker can make a connection to it".
I hope you find this useful.
