[rails] Как импортировать seed данные с id в postgresql?

namespace :db do
  desc "Установить все счётчики ID в актуальное значение"
  task :reset_seq => :environment do
    query = "SELECT  'SELECT SETVAL(' ||quote_literal(quote_ident(S.relname))|| ', MAX(' ||quote_ident(C.attname)|| ') ) FROM ' ||quote_ident(T.relname)|| ';'
FROM pg_class AS S, pg_depend AS D, pg_class AS T, pg_attribute AS C
WHERE S.relkind = 'S'
    AND S.oid = D.objid
    AND D.refobjid = T.oid
    AND D.refobjid = C.attrelid
    AND D.refobjsubid = C.attnum
ORDER BY S.relname;"
     ActiveRecord::Base.connection.execute(query).each{ |s| ActiveRecord::Base.connection.execute(s["?column?"])}
  end
