I have been working on a plugin for GiST that has some unusual features:
* The data type for both Node and Leaf keys is large (typically 4222
bytes on 32-bit; 4230 bytes on 64-bit).
* Due to the large size the storage class is EXTENDED (main would only
degrade to EXTENDED in any case). Tes
ngerprint = f2.fingerprint)
(The previous query example used the ~= operator which was defined to
match at > .5 but in this case there no matches in the table so ~= is
the same as =.)

I'll put together a test case and send that on.

I should correct what I just wrote: the first and last entries in
entryvec->vector are invalid.

Picksplit() seems to be an exceptional case here: the first and last

entryvec->vector[entryvec->n - 1]
is invalid. All the other GiST code Picksplit() functions use the
same convention. For example, see the btree_gist picksplit function, at

2000 bytes in size. So GiST definitely handles large keys. Perhaps the
maximum size for intarray could be increased.
