Well, what that's mostly going to result in is a huge amount of
duplication :-(. psql, pg_dump, and anything else that wants to support
this will need some alternative command line switch and an alternative
code path to call PQstartServer. I'd hoped to avoid all that. Note
that the POC patch involved not one single line of change in those
application programs.
