Hm.  Before we add a bunch of code to deal with that, are we sure we
*want* it to copy such files?  Seems like that's expending a lot of
data-transfer work for zero added value --- consider e.g. a server
with a bunch of old core files laying about in $PGDATA.  Given that
it's already excluded all database-data-containing files, maybe we
should just set a cap on the plausible size of auxiliary files.
