This commit reverts 1adf16b8fb, 87c21bb941, and subsequent fixes and improvements including df64c81ca9, c99ef1811a, 9dfcac8e15, 885742b9f8, 842c9b2705, fcf80c5d5f, 96c7381c4c, f4fc7cb54b, 60ae37a8bc, 259c96fa8f, 449cdcd486, 3ca43dbbb6, 2a679ae94e, 3a82c689fd, fbd4321fd5, d53a4286d7, c086896625, 4e5d6c4091, 04158e7fa3. The reason for reverting is security issues related to repeatable name lookups (CVE-2014-0062). Even though 04158e7fa3 solved part of the problem, there are still remaining issues, which aren't feasible to even carefully analyze before the RC deadline.

test_ddl_deparse is an example of how to use the pg_ddl_command datatype. It is not intended to do anything useful on its own; rather, it is a demonstration of how to use the datatype, and to provide some unit tests for it. The functions in this extension are intended to be able to process some part of the struct and produce some readable output, preferably handling all possible cases so that SQL test code can be written.
