The new format allows for downloading and importing only a part of the
database - useful when only the metadata is required - and doesn't
include the wasteful preformatted HTML cache.
This also ensures that the new import.sql script is actually usable and
in sync with the actual database. The old schema.sql was neither.
(And this simplifies my backup scripts)
Seems to be working alright, and it does clean up a few things. The
biggest missing thing right now is schema-based validation for some
query parameters. I'm also seeing opportunities for FU::Pg to act as a
hash/shorthash codec, simplifying some error-prone manual conversions.
