That's got nothing to do with it being a two-column index --- it's that
GiST doesn't know what to do with a timestamptz, in any column.
I see that there is support for timestamp without time zone in
contrib/btree_gist --- probably it would be a simple matter to extend
that to timestamp with time zone. But it's not there today (much less
in 7.3 ;-))
