Client is pgAdmin from the 8.3.3 installer.

client=warning, log=warning completes
client=warning, log=notice fails
client=notice, log=warning completes
client=notice, log=notice fails

It fails a heck of a lot quicker with client=warning, log=notice.

This is the raise that causes it
CREATE OR REPLACE FUNCTION stagecode(date, date)
RETURNS text AS
$BODY$
declare
TimeSpan integer = $2 - $1;
begin
raise notice '%',TimeSpan;
return
case when $1 is null or $2 is null then 'X'
when TimeSpan < 10 then 'B'
when TimeSpan < 70 then 'L'
when TimeSpan < 120 then 'W'
when TimeSpan < 330 then 'P'
when Timespan < 450 then 'Y'
when Timespan < 700 then 'H'
else 'A'
end;
end;$BODY$
