Postgres update

Includes changes from N52 wps 3.3.0 upgrade  branch
This came from:
072f1d5 - abramhall <abramhall@usgs.gov> Jun 18, 2014
add methoed to strip the UTF byte order mark (BOM) if it's there, as it breaks SAX parsing

I'm not interested, currently, on dealing with testing/removing this. After this large request is merged in, we should come back and look at this.
