probably such a limitation may exists in db2 also.
I think the gap is genuine.

Recently I have been put on a project that uses DB2 (not my choice). I am using functions for reports and was told this may not be allowed. They said:One gap is the ability to tune the code in the function (not really static) or to perform real-time analysis of performance problems.

I normally use PostgreSQL for all my applications (this being an exception). Does anyone know what this statement is about and, more importantly, does PostgreSQL have the same limitations?
Thanks,
