pg v0.5.1.3 Release Notes

Release Date: 2016-05-01 // almost 8 years ago

    • 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.
