I'm not entirely sure I know what's going on here, but I'm pretty sure
that it makes no sense for the new float8_pl function to reject
non-aggregate callers at the beginning and then have a comment at the
end indicating what it does when not invoked as an aggregate.
Similarly for the other new function.
It would be a lot more clear what this patch was trying to accomplish
if the new functions had header comments explaining their purpose -
not what they do, but why they exist.
float8_regr_pl is labeled in pg_proc.h as an aggregate transition
function, but I'm wondering if it should say combine function.
The changes to pg_aggregate.h include a large number of
whitespace-only changes which are unacceptable. Please change only
the lines that need to be changed.
