BLCKSZ, in src/include/pg_config_manual.h. I doubt it would make the
index faster anyway ... I think you could post the query, schema, and
EXPLAIN ANALYZE to pgsql-performance so that people can give you further
advice. Going forward, rtree is somewhat obsolete -- maybe try setting
up a GiST index instead (not sure if it would be faster than rtree.)
