postgresql-simple v0.4.0.0 Release Notes

Release Date: 2013-12-21 // over 10 years ago

    • Changed the calling code of fromField so that it always sends a copy of the raw data. This should be a small but significant performance bump for most people most of the time; however it may slow down retrieval of large values not converted directly to ByteString, such as large json, hstore, and array values. See commit 8635f8 for more information.

    • Added the PGArray type. Thanks to Joey Adams for the suggestion

    • Fixed JSON decoding, which was almost entirely broken up until now, due to bugs in the version of aeson currently available on Hackage. Thanks to Amit Levy for the report.

    • Added FromField instances for IORef, MVar, and IOVector.
