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. Thanks in advance.
