There's no chance that would get included in pacman 2.9.8 - it will die soon.

Converting it to pacman3 is entirely doable and it's already setup to
do so.  You should be able to copy be_files.c to be_gdbm.c and consume
the interface provided there.

FTR 'be_' means 'backend'.  I still need to add compile-time flags for
selecting a backend, but as we only provide _files at the moment,
there's no need.

I worked on a 'compressed' backend that required no changes, but read
directly from the downloaded db files... it caused problems on the
local db, however, so I never completed it (yet).

As for backend schemes, I think we need to discuss avenues of attack
here.  The files backend is painfully slow on ext filesystems (11
seconds to parse [community]).  There are many users touting a
database backend as a good idea (I highly disagree), and if we do
this, we NEED a generic layer to support any sane database format, not
just one specific thing.  Using a flat-file database is a better
option, but here people seem to think sqlite is a good idea (it's not)
- there are many flat-file schemes that can drastically outperform

There are many many other options, and I think it's worth at least
_supplying_ multiple backends, even if they're not used.  So gdbm is
