Sorry, that's wrong.  The correct usage would be:
ogr2ogr -where "entity_type='SomeParticularType'" reduced.shp original_full.shp

(the single and double quotes need to be in that order)

Also, for postgis input and shape output you'd just do:

ogr2ogr -f "ESRI Shapefile" -where "enity_type='SomeParticularType" output.shp \
     PG:'dbname=russo' input_table_name

HTH,
