It looks like the GIST code expects your compress function to give back
a varlena datatype, not the fixed-length type you are actually handing
back. The ridiculous length comes from interpreting the first word
of your BOX3D as a length.
There are/were provisions in the GIST code for having the compress
function emit a different datatype than it takes in, but I think they
are incomplete or broken. Might be easiest to produce a varlena result
for now.
