This is an implementation of RD-tree data structure using GiST interface
of PostgreSQL. It has built-in lossy compression - must be declared
in index creation - with (islossy). Current implementation has index support
for one-dimensional array of int4's.
in index creation - with (islossy). Current implementation provides index
support for one-dimensional array of int4's - gist__int_ops, suitable for
small and medium size of arrays (used on default), and gist__intbig_ops for
indexing large arrays (we use superimposed signature with length of 4096
bits to represent sets).
All work was done by Teodor Sigaev (teodor@stack.net) and Oleg Bartunov
(oleg@sai.msu.su). See http://www.sai.msu.su/~megera/postgres/gist
for additional information.
