) INHERITS (father);

Subject: [GENERAL] partitoning expert : Partitonning with specialization of one column type
for partitionning expert.
I have several table child with columns (gid serial, patch pcpatch(n))
where n may change depending on the tables, and pcpatch is a type from pgpointcloud extension
(here is the definition)
-----
CREATE TYPE pcpatch
(INPUT=pcpatch_in,
OUTPUT=pcpatch_out,
RECEIVE=-,
SEND=-,
TYPMOD_IN=pc_typmod_in,
TYPMOD_OUT=pc_typmod_out,
ANALYZE=-,
CATEGORY='U', DEFAULT='',
INTERNALLENGTH=-1, ALIGNMENT=int4, STORAGE=MAIN);
-----
The question is, how do I create an inheritance scheme?
If the father table is
CREATE TABLE father(
trying to put child_1, child_2 ... to inherit father raise an error
----
child table "test_child_1" has different type for column "patch"
----
So my question is, how would it be possible (if at all) to inherit of father table, while specializing the type of father table in child table?
