Trying this (in python)

uri.setConnection(host, port, dbname, user, passwd)
uri.setDataSource(schema, table, geom_column)
uri.setSql('LIMIT 10')

vl = qgis.core.QgsVectorLayer(uri.uri(), layername, "postgres")

terminal displays this error
row number 0 is out of range 0..-1

so this query returns no rows.
