Multi-column gist indexes are basically useless at this point. The index pages
are split based entirely on the first column, so the index becomes basically
an index on the first column.
There was some discussion on changing this but there wasn't consensus on which
direction to head with it. It may come up again for 8.1 if someone wants to
look at it.
