PostgreSQL arrays can have a lower bound different from 1 http://www.postgresql.org/docs/9.4/static/arrays.html. Such arrays are also returned by some fields in the pg system catalogs. Example to produce such an array:...
Hi, Looking over: http://hackage.haskell.org/package/postgresql-simple-0.4.10.0/docs/Database-PostgreSQL-Simple-FromField.html It seems we are missing support for geometric datatypes, in particular, point. See: www.postgresql.org/docs/9.4/static/datatype-geometric.html Kind Regards, Edward.
Since postgresql-simple just throws IOExceptions, it's really hard to deal with meaningful differences in exceptions, such as closed connections. I had to add this to my code to deal with...
Issues #122, #123, and #124 that affected `UTCTime` also applies to `ZonedTime`. Unfortunately, the `time` package's conception of `TimeZone` is very much deficient. `TimeZone` is defined as: ``` data TimeZone...
