Hello everyone,
I plan to directly construct a query plan without going through the query
optimizer, by manipulating the various data structures for representing
query plan tree and parse tree. Is there any facility inside/outside
postgresql that can be of help? Is there any known issue/difficulty related
to this?

Thanks!

Steve
