I see that the benchmarks were run on a laptop with storage systems
which are not typical of what one would see on a database server,
so it is hard to predict how things would shake out on a real
server. Those are some intriguing numbers, though.

Did you look at the FDW page, and in particular the "black hole"
template FDW? If someone familiar with LMDB wanted to fill in the
stubs from that template to provide a working lmdbfdw extension, I
would bet that there are people who would be interested in running
a few of our standard benchmarks against real server hardware to
see how it performs.
