 I found that I was not able to add filters on PostGIS layers while the
 "Render" option in the lower right hand corner is unchecked.  The idea was
 to add a layer, stop the rendering, add a filter on my layer, and *then*
 to render (to save bandwidth).

 After unchecking "Render," I right-clicked on the layer, and went to
 Properties-> General-> Query Builder.  I received a database error for
 every WHERE clause I wrote.  After clicking "cancel," I checked the
 "Render" option, navigated back into the Query Builder, and was able to
 use WHERE clauses that previously failed.
