Dmitry provided me with a test case, from which it became apparent that
the problem was the new bitmap indexscan code not being fully ready to
cope with partial indexes. There were a number of problems besides the
core dump itself, but I think I've got it all cleaned up now.

TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match
