Hi Andrew,

woooh .... sounds like giving the advice to reduce the usage of user
defined functions to a minimum. But in my opinion it should be a good
idea to move functionality to the database in case you work with a
Language like PHP. As I recognized it is a good idea to do so 'cause the
database is often faster than PHP.

I am speaking of PL/pgsql and SQL udf's.

Did I misunterstand you? Are there other experiences? In which cases is
the planner forced to have problems with statements containing udf's?

Cheers

Andy
