...I was hoping not to have to implement the date type, because date
conversions suck, but it turns out manned.org actually needs it.
(Only to then convert it into a Unix timestamp again, hmm, maybe this
string conversion isn't useful at all?)
NOW we're really getting to the part where this module is more awesome
than DBD::Pg.
(When I started working on this module I was expecting that the Postgres
binary protocol would send jsonb in a binary format as well and that I'd
be duplicating parts of the JSON parser/formatter to make that work, but
it turns out that Postgres just uses plain json for exchange. Saves me
some trouble, I guess)
