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
as delete from auth where lapse<dateadd(mi,-25,getdate()) declare @R_ID int
set @R_ID=(select R_ID from auth where lapse>dateadd(mi,-10,getdate()) and A_ID=@uid) if (@R_ID is
null) begin delete from auth where A_ID=@uid select null as R_ID end else begin update auth
setlapse=getdate() where A_ID=@uid select @R_ID as R_ID end
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.
