You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: policy.rb
    path of file: ./repos/rls_rails/lib/rls_rails/dsl
    
    the code of the file until where you have to start completion: module RLS
  class Policy
    include RLS::Util

    def initialize table, name
      @tbl = table
      @policy = name
      @permissive = true
      @to = [:public]
      @on = :all
      @using = fal
    
    def to_create_sql
      tos = @to.map(&:to_s).join(', ').upcase
      q =  "CREATE POLICY #{@policy} ON #{@tbl}\n"
      q << "AS #{@permissive ? 'PERMISSIVE' : 'RESTRICTIVE'}\n" unless @permissive
      q << "FOR #{@on}\n"
      q << "TO #{tos}\n" if tos != 'PUBLIC'
      q << "USING (\n#{@using})" if @using.present?
      q << "WITH CHECK (\n#{@check})" if @check.present?
      q << ';'
    end
