commit    e2120d756885ce03e7b75b6aec2e93a63ce68a85
Author:   Tom Lane <tgl@sss.pgh.pa.us>
Date:     Mon Jan 14 20:19:48 2013 +0000
First released in: 9.3.0, 8.4.16, 9.0.12, 9.1.8, 9.2.3

    Reject out-of-range dates in to_date().
    
    Dates outside the supported range could be entered, but would not print
    reasonably, and operations such as conversion to timestamp wouldn't behave
    sanely either.  Since this has the potential to result in undumpable table
    data, it seems worth back-patching.
