I think I'll have to work with pg 7.3
Does this translate to: you won't be able to use variables?
I was used to do stuff like this with MS SQL
create proc sp_getuid @uid uniqueidentifier
delete from auth where lapse<dateadd(mi,-25,getdate())
declare @R_ID int
set @R_ID=(select R_ID from auth where
if (@R_ID is null)
delete from auth where A_ID=(at)uid
select null as R_ID
update auth set lapse=getdate() where A_ID=(at)uid
select @R_ID as R_ID
Does it mean that to have variables in SP I'll have to use plpgsql
in spite of plain SQL?

TY for the refreshing pointer. I was looking in the wrong place.
