no -- it's actually possible for some trivial things (just grabbing a
few tables) -- but anything more complicated will quickly become
unreasonably difficult.
TBH, I think backups through SQL are quite nice. Judging by the
standard of other databases, I generally always prefer the sql version
to the command line variant with both tools are available.
It would also be nice to be able to generate a restorable script from
any userland object. pg_dump/pg_restore gives you the ability to
specifically grab indexes, functions, table, and triggers, but that's
it.
