To all,<br /><br />I am brand new to writing functions for PostgreSQL and understand that this question has been asked
onehundred and one times. Please be patient with me, I do learn quickly.<br /><br />My question is:<br /><br />I wish
tocreate a an aggregate function and have read and re-read the 34.10 section of the 8.3 documentation as well as
scannedthrough the fmgr header file. My problem is that I know certain structures are created with the idea of
retaininginformation for use in the state function but I don't really understand which structures I should be looking

amusing the Version 1 calling convention.<br /><br />Thanks in advance.<br /><br />Aaron <a name="XAGGR"><span
