Not I, but I can give you some background. The crash seems to only
occur when the argument of the GROUPed by function is not used elsewhere
in the target list.
example:
select upper(usename), count(usename) from pg_shadow group by 1;
OK
select upper(usename), count(oid) from pg_shadow group by 1;
CRASH
It did work in 6.3.
