Q: Comparing PostgreSQL and Oracle

Hi colleagues.


I'm working in a Java application with some colleagues and we are in 
doubt wether to use Oracle or PostgreSQL as the data store. It will be a 
OLTP mainly application.

Beside of license terms/costs  which is a clear point in favor of 
PostgreSQL, could you please help me to get some more details regarding 
what you can do in PostgreSQL and you can't in Oracle oand viceversa, 
and what can be done using both but it is better done by PostgreSQL vs 
Oracle and so on?

I mean, about functionalities, performance, support costs if any and 
qualtity, etc.


Many thanks.

Best Regards.
