Package: python-pygresql
Version: 1:3.6.1-1
Severity: normal
Tags: patch
When passed an mx.DateTime instance on a locale where the decimal
separator is a comma (',') an invalid SQL string will be generated.
Processing mx.DateTimeDelta (e.g. for time values created by pgdb.Time
constructor) is not supported at all.
Date- and Time-values are returned as 'strings', instead of a
proper mx.DateTime* instance (as stated by the constructors Date, Time
and Timestamp).
The added patch should solve these problems.
