crash in Result.prototype.parseRow

[spollack]

this is running pg 4.5.1 javascript, with PR #949 on top. crash happened in production (just once so far). we do not currently have a repro case.

TypeError: object is not a function
    at Result.parseRow (/app/node_modules/pg/lib/result.js:61:10)
    at Query.handleDataRow (/app/node_modules/pg/lib/query.js:58:26)

    at TCP.onread (net.js:529:21)

The offending bit of code is:

Result.prototype.parseRow = function(rowData) {
  return new this.RowCtor(this._parsers, rowData);
};

Is this another instance of #949 (comment)?
