of PostgreSQL. It has built-in lossy compression.
Current implementation provides index support for one-dimensional array of

integers: gist__int_ops, suitable for small and medium size of arrays (used by
default), and gist__intbig_ops for indexing large arrays (we use superimposed

signature with length of 4096 bits to represent sets). There is also a
non-default gin__int_ops for GIN indexes on integer arrays.
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
