Version 0.5.3.0 (2017-05-15)

• Refactored some rudimentary cursor handling code out of the implementation of the fold operators, into a new Database.PostgreSQL.Simple.Cursor module, thanks to Bardur Arantsson.

• Made the FromField instance for Char compatible with postgresql's bpchar type. Thanks to Ivan Lazar Miljenovic for reporting the issue.

• Added Show and Eq instances for Notification, thanks to Matvey Aksenov.

• Fixed some example code, thanks to Matvey Aksenov.

• Fixed a problem with using conversionError to throw exceptions of type SomeException. Previously, the exception would be wrapped in a second SomeException dynamic constructor which would cause normal GHC typecase idioms over SomeException to fail.
