This version fixes this problem, so the regression tests now pass.
I fixed it by adding yet another index attribute bitmapset to
RelationData, so we keep track of "all indexed columns" separately from
"columns used by regular indexes" and "columns used by indirect
indexes". A possible optimization is to remove the first list and just
keep "indirect" and "direct", and in the only case where we need all of
them, do a bms_union -- it's not performance-critical anyway.
