I'm not claiming, I'm asking, because I can't tell. 

And it's not clear _int_gist.c has been running with toasted array values for
years because it's limited to arrays of 100 integers (or perhaps 200 integers,
there's a factor of 2 in the test). That's not enough to trigger toasting
unless there are other large columns in the same table.

I do know that with packed varlenas I get a crash in g_int_union among other
places. I can't tell where the datum came from originally and how it ended up
stored in packed format.
