What I'd really like, in addition to this, is a way to extract a query
from an $st object that can be run in the psql CLI. VNDB has a debugging
feature for that, but it's less trivial to make that work with binary
query parameters.
Realized that, since html_() now returns a string, it's just as easy to
just pass that to fu->set_body(); no need for integration complexity.
Combined import options don't save much typing, not worth the overhead
either.
