Commit 5adff6ff0b88d6f162719eff7176069730537c2a separated the data copy from creating table. This is a cause of bug that pg_repack doesn't actually sort table during reorganization. This commit fixes this issue by adding ORDER BY clause to Copy SQL rather than CREATE TABLE SQL. Reported by acmzero on issue #138.

pg_repack_ is a PostgreSQL extension which lets you remove bloat from
tables and indexes, and optionally restore the physical order of clustered
indexes. Unlike CLUSTER_ and `VACUUM FULL`_ it works online, without
holding an exclusive lock on the processed tables during processing.
pg_repack is efficient to boot, with performance comparable to using
CLUSTER directly.
Please check the documentation (in the ``doc`` directory or online_) for
installation and usage instructions.

What about pg_reorg?
--------------------
pg_repack is a fork of the pg_reorg_ project, which has proven hugely
successful. Unfortunately new feature development on pg_reorg_ has slowed
or stopped since late 2011.
pg_repack was initially released as a drop-in replacement for pg_reorg,
addressing some of the shortcomings of the last pg_reorg version (such as
support for PostgreSQL 9.2 and EXTENSION packaging) and known bugs.
pg_repack 1.2 introduces further new features (parallel index builds,
ability to rebuild only indexes) and bugfixes. In some cases its behaviour
may be different from the 1.1.x release so it shouldn't be considered a
drop-in replacement: you are advised to check the documentation__ before
upgrading from previous versions.
