Mark,
we prepared new version of contrib-intarray -
index support for 1-D integer arrays using GiST.
Changes:
- Improved regression test
- Current implementation provides index support for one-dimensional array of int4's - gist__int_ops, suitable for
smalland medium size of arrays, and gist__intbig_ops for indexing large arrays (we use superimposed signature with
lengthof 4096 bits to represent sets, see Sven Helmer,1997).
