This week I have been to Southern Germany. This customer has sucessfully
migrated from Oracle to PostgreSQL. With the help of a gborg package
(Oracle style data dictionary) and CREATE DOMAIN they were able to run
there current application WITHOUT modification.
There was just one thing we have encountered:
SELECT * FROM X MINUS SELECT * FROM X
does not work on PostgreSQL (we use EXCEPT instead).
This small patch fixes this problem.
Maybe it improvements can be integrated into 7.6
