Add optional compression method to SP-GiST
Patch allows to have different types of column and value stored in leaf tuples
of SP-GiST. The main application of feature is to transform complex column type
to simple indexed type or for truncating too long value, transformation could
be lossy. Simple example: polygons are converted to their bounding boxes,
this opclass follows.
