pgstatspack pg_stat_statements error

[Brett Gaston <bgaston@xxxxxxxx>]

When I load pg_stat_statements in the shared library and try to run a pgstatspack snapshot, I get the following errors:  I am running version 2.3.1.  Ironically, if I don't load load pg_stat_statements in the shared library, I don't get these errors when running a snapshot although I do get log warnings that I should load pg_stat_statements.  Anyone have an idea of what the issue could be?
