To all,
I am brand new to writing functions for PostgreSQL and understand that
this question has been asked one hundred and one times. Please be
patient with me, I do learn quickly.
My question is:
I wish to create a an aggregate function and have read and re-read the
34.10 section of the 8.3 documentation as well as scanned through the
fmgr header file. My problem is that I know certain structures are
created with the idea of retaining information for use in the state
function but I don't really understand which structures I should be
looking at and how to initilize them (if needed) in the sfunc. Any
pushes in the right direction would be very appreciated, I am using
the Version 1 calling convention.

This is not the correct forum for such questions. Please ask again on
pgsql-general. pgsql-hackers is about development of postgresql itself.
