The following bug has been logged on the website:

Bug reference:      7763
Logged by:          Norbert Buchmuller

PostgreSQL version: 9.2.2
Operating system:   Linux 2.6.32, i386, Debian GNU/Linux 6.0.5
Description:        =


There's a table that has a B-Tree index on a composite type expression. When
attempting to create another table just like the first table and with the
indexes also "copied" using the "CREATE TABLE ... (LIKE ... INCLUDING
INDEXES ...)" statement, it throws an error (see below) and the table is not
created.

I believe it's a bug, from the documentation i assumed that it should create
the table with a similar index, no matter that the index is on a composite
type expression.

CREATE TYPE type1 AS (x int, y int);
CREATE TABLE table1 (a int, b int);
CREATE INDEX index1 ON table1 ( ( (a, b)::type1 ) );
CREATE TABLE table2 ( LIKE table1 INCLUDING INDEXES );
\d table2
