Please can you answer the question of whether entry->key in compress should
be of delta3d sql type (composite type) and if not of what it should be
since the type I index is different from the type stored in tree?
Taking into consideration the types I described before this is my code for
compress.

Yes ofcourse, I also read everything in postgresql official documentation
plus http://gist.cs.berkeley.edu/pggist/opcltour.html.

Let me explain better what I want to do.
I want to have the types in sql level (composite types) like this:
--Spatio-Temporal Position in 3 Dimensions(cartessian x, cartessian y, time)
CREATE TYPE pos3d AS
(
x double precision,
y double precision,
t timestamp
);
--Spatio-Temporal Delta (com

If I have this sql composite type:
CREATE TYPE d_type AS
(
i integer,
e integer,
id integer
);
and this table:
CREATE TABLE my_tab
(
d_col d_type NOT NULL
)
CREATE INDEX my_tab_d_col_gist ON my_tab USING gist (d_col);
I am implementing consistent, union, compress, decompress, penalty,
