  • v0.5.3.0 Changes

    May 15, 2017
    • 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.

  • v0.5.2.1 Changes

    June 29, 2016
    • Bumped the lower bound for base to 4.6. Thanks to Herbert Valerio Riedel for reporting the issue.

    • Added an Eq instance for SqlError, thanks to Chris Allen

    • Fixed a bug where a all-caps "NULL" text value inside a postgresql array would get parsed as the SQL null value. Thanks goes to Edgar Gomes and Silk for finding and fixing this mistake.

    • Modified withTransaction and friends to ignore IOErrors when attempting to roll back the transaction. This fixes a buggy interaction between withTransaction and async exceptions (e.g. System.Timeout) on unix platforms. Thanks goes to Erik Hesselink and Silk for providing the test case that exposed this issue.

    • Added the testTimeout regression test for the problem above.

  • v0.5.2.0 Changes

    May 25, 2016
    • Significantly improved the error reporting from Copy.putCopyData, thanks to Ben Gamari.

    • Moved the test suite to use tasty, with a big thanks to Ben Gamari.

    • Added FromField.optionalField, and updated the documentation of FromField.fromJSONField, as inspired by an email conversation with Ian Wagner.

    • Updated all links in the haddocks to use https, and added a link to the documentation of connectPostgreSQL.

    • Added a truncated changelog to the source distribution.

  • v0.5.1.3 Changes

    April 30, 2016
    • Implemented the Monad of No Return proposal, future-proofing postgresql-simple against future releases of GHC.

    • Fixed a rare and usually benign race condition where getNotification could end up waiting on a newly reallocated file descriptor index, potentially leading to deadlock if the descriptor does not become readable promptly. This fix only applies to GHC 7.8 or later, as it depends on threadWaitReadSTM.

    • Tweaked the time parsers to accept times of day of the form hh:mm, omitting seconds, following changes made to aeson.

    • Updated the documentation of the In type to point out a gotcha when using the SQL fragment ... NOT IN ? with In []. Thanks goes to Simon Michael and Dan Haraj for bringing this issue to my attention.

  • v0.5.1.2 Changes

    December 14, 2015
    • The syntax generated for empty arrays was changed so that postgresql's type inference would work better, thanks to Amit Levy.

    • Further revision and expansion of the new Time documentation.

  • v0.5.1.1 Changes

    December 02, 2015
    • This is a documentation-only release

    • The documentation of the Time module has been completely rewritten, and is far longer and more informative. It contains a brief overview of civil time, the semantics of postgresql's time types, and their relation to Haskell's time types via postgresql-simple.

    • The documentation of connectPostgreSQL has been modified to mention the effects of environment variables on the connection string parameters.

    • The documentation of HStore.Internal has been unhidden from haddock.

    • A typo in example code was fixed courtesy of Levi Notik.

  • v0.5.1.0 Changes

    October 22, 2015
    • Optimized the implementation of the streaming operators to avoid creating intermediate lists of rows, thanks to Timo von Holtz.

    • Added default instances for ToRow and FromRow that depend on Generics, thanks to Alexey Khudyakov.

    • Fixed support for bytestring-0.9 and GHC 7.4.

  • v0.5.0.1 Changes

    September 21, 2015
    • Fixed a bug when printing a ZonedTime with a negative offset that is not a whole number of hours.
  • v0.5.0.0 Changes

    September 19, 2015
    • Removed the deprecated BuiltinTypes module.

    • Modified the SQL quasiquoter so that it returns a Query, not an overloaded string, and so that the OverloadedStrings language extension is no longer necessary, thanks to Mike Ledger.

    • Moved away from blaze-builder in favor of bytestring-builder. This shouldn't affect very many people, but does reduce the transitive dependencies.

    • Rewrote the timestamp printers to use the new Prim infrastructure in bytestring-builder. The new printers should be a fair bit faster.

    • Added support for exclusion violations to the ConstraintViolation type in the Errors module, thanks to João Cristóvão.

    • Moved away from the uuid package in favor of the uuid-types package, thanks to Bardur Arantsson. This shouldn't affect anybody, but does reduce the transitive dependencies.

    • Postgresql-simple now explicitly assumes the UTF8 character encoding for communication between the client and server. All database encodings support UTF8 except for Mule Internal Code, the Multilingual Extensions for Emacs. An exception should be raised upon connecting to a database by the backend if the backend cannot accomodate this requirement.

    • Added Eq and Typeable instances for Connection.

    • Added the foldWith, forEachWith, and returningWith families of functions courtesy of Travis Staton.

    • Support for Ranged types, with thanks to Leonid Onokhov for his contributions.

    • The FromField instance for JSON now allows for top-level values that are not objects or arrays, thanks to Sam Rijs.

    • The timestamp parsers have been replaced with those now in Aeson. Janne Hellsten adapted the old parsers from postgresql-simple for inclusion in Aeson; Bryan O'Sullivan rewrote those parsers to be faster, with some tweaks contributed by myself. And now to bring the effort full circle, the result has been brought back to postgresql-simple, with some adaptations.

    • Fixed a bug in the typeinfo system where postgresql's _record type was being reported as a basic type and not an array type. Thanks to Nickolay Kolev for helping to expose this issue.

    • Fixed a bug with the typeInfo operator, thanks to Timmy Tofu. In the case of parsing subfields of arrays and composites, it would fetch the TypeInfo of the array or composite type and not the subtype.

  • v0.4.10.0 Changes

    February 26, 2015
    • Added a blurb about SSL/TLS in the documentation for connectPostgreSQL

    • Moved some functions into the Internal module, courtesy of Aleksey Uimanov.
