I'll take the blame for the aggregate issue ;-).

SFUNC1/STYPE1/INITCOND1 in 7.0 equate to SFUNC/STYPE/INITCOND in 7.1.
There is no 7.1 equivalent to 7.0's SFUNC2/STYPE2/INITCOND2 --- those
have to be saved/restored separately if you are dumping a 7.0 database
with intentions of restoring it to 7.0.  On the other hand, if you are
dumping 7.0 with an eye to restoring to 7.1, you could just as well
raise an error if those fields are nonnull.

Assuming 'proisstrict' for a 7.0 function seems reasonable.
