Log Message:
Updated py-sqlparse to 0.2.1.

Release 0.2.1 (Aug 13, 2016)
---------------------------

Notable Changes

* PostgreSQL: Function bodys are parsed as literal string. Previously
  sqlparse assumed that all function bodys are parsable psql
  strings (see issue277).

Bug Fixes

* Fix a regression to parse streams again (issue273, reported and
  test case by gmccreight).
* Improve Python 2/3 compatibility when using parsestream (isseu190,
  by phdru).
* Improve splitting of PostgreSQL functions (issue277).
