It looks to me like you need to read the documentation on this topic. http://www.postgresql.org/docs/current/static/gist-implementation.html From what I can gather from said documentation, consistent will indeed get the data type as an argument, but compress does not. You might also want to look at contrib/btree_gist. > Something else, will a non-leaf node have one entry that will be produced by > union?

I don't think this is a good idea. I suspect you want to keep the id attribute never, and use the recheck stuff. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise Postgres Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
