Update 1.11.1 --> 1.11.2
Major changes in 1.11.2 (2013-04-12)
This is a bugfix release.
* Incremental propagation could erroneously act as if a slave's
database were current after the slave received a full dump that
failed to load.
* gss_import_sec_context incorrectly set internal state that
identifies whether an imported context is from an interposer
mechanism or from the underlying mechanism.
Feature safe: yes
