Is this the wrong list?

On Mon, 14 Aug 2000, I wrote under the subject "Any SQL-functions examples
available":

Is there any other list where I could expect answers to those simple
questions.  I could not imagine that nobody has ever written some
simple tests with SQL functions.  Perhaps this problem is to simple
here.

Or may be I have the wrong philosophy and those functions are not
ment to be used in PostgreSQL?

Kind regards
