Having lots of interested people doesn't help with some problems,
though. The Citus document says:
And the issue with these four limitations wasn't with foreign
data wrappers. We wrote mongo_fdw and cstore_fdw, and we're
quite happy with the contract FDWs provide. The problem was that
we were trying to retrofit an API for something that it was
fundamentally not designed to do.
