title: postgresql change character varying to character varying array
body: <p>below I have two columns in table. they both say they are character varying but zoning_description has an array symbol after it. I need to change the zoning column to match the zoning_description column type. how do I accomplish this.</p>
  
  <p>Also what is the difference between these two column types...
  I am running into an error later in a different process because of this problem</p>
