It has built-in lossy compression. 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 +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). +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).
