mplement a SP-GiST index too.
Thanks!

Never mind, it turns out the issue boiled down to me declaring the
wrong prefixType in my config function.
TL;DR - PEBKAC

for example.
I think this is the SP-GiST core failing to handle certain types being
pass-by-value? I'm not totally certain.
As I understand it, the "maybe-pass-by-reference" parameter is a global
flag (USE_FLOAT8_BYVAL), but I'd like to
keep that enabled. What&#
umb questions. Postgresql is huge and I have
no idea what I'm really doing.

The existing VP-tree code appears to not support multiple operators

Hi there!
I'm looking at implementing a custom indexing scheme, and I've been
having trouble understanding the proper approach.
Basically, I need a BK tree, which is a tree-structure useful for
indexing arbitrary discrete metric-spaces (in my case, I'm interested in
indexing across the hammi
rs mailing list for that. Also, do you want GiST
or SP-GiST ?
We already use hamming distance in rd-tree, which implemented in GiST,
