Is the following description now outdated:
"ForeignPath represents a potential scan of a foreign table"
Considering that there now exists FdwRoutine.GetForeignJoinPaths() whose
product is nothing else but a ForeignPath, should it now say (patch attached):
"ForeignPath represents a potential scan of foreign table(s)"
Or something better.
I think it'd be better to match the comment with that for
create_foreignscan_path(). So how about "ForeignPath represents a
potential scan of a foreign table, foreign join, or foreign
upper-relation processing"? I think we would probably need to update
the comment in src/backend/optimizer/README (L358), too.
