inputs/.geoscrub/geoscrub_output/postprocess.sql: added nullable unique index on the inputs, for use by analytical_stem_view. note that it must be nullable in order to create a match when not all of the input fields are populated. this uses array[] to create a nullable index, which is much better than column-based import and VegBIEN's use of COALESCE because the expression is the same for every type and no NULL sentinel value is needed.
