Telling people who've already installed and configured an FDW that for
perfectly ordinary expected functionality they'll need to install yet
another piece of software, configure it, keep its configuration in
sync with the FDW configuration, etc., is just a ridiculous. So yes,
we do need this functionality and it does need to be part of our FDW
implementation.

Just exactly where we draw the line between built-ins and APIs is the
conversation I thought we were having. The minimal thing would be
providing database handles per SQL/MED and a few tools to manipulate
same.

Cheers,
David.
