Greetings!

Not sure if this might be a 9.4 regression or if the FDW interface has
changed and tds_fdw needs some tweaking, however:

When I join a local table with a view on a foreign table (tds_fdw), I get

TRAP: FailedAssertion("!(outer_rel->rows > 0)", File: "indxpath.c", Line:
1861)

and the server restarts.

This is reproducable and happens even when EXPLAINing the query.

The forreign table, the view and the local table can be accessed normally,
also when filtering by the columns used for the crashing join.

Cheers,

Nick
