Robert Haas b30fb56b07 postgres_fdw: Push down FULL JOINs with restriction clauses.
The previous deparsing logic wasn't smart enough to produce subqueries
when deparsing; make it smart enough to do that.  However, we only do
it that way when necessary, because it generates more complicated SQL
which will be harder for any humans reading the queries to understand.
