Issue with strictness and security with tracing procedure

[lcoldiron]

lib/piggly/dumper/prodcedure.rb around line 50 needs to be modified to work with strictness and security keywords.

before:

Returns source SQL function definition statement

  # @return [String]
  def definition(body)
    [%[create or replace function "#{@namespace}"."#{@name}" (#{arguments})],
     %[ #{strictness} #{security} returns #{type} as $**PIGGLY**$],
     body,
     %[$**PIGGLY**$ language plpgsql #{@volatility}]].join("\n")
  end

after:

Returns source SQL function definition statement

  # @return [String]
  def definition(body)
    [%[create or replace function "#{@namespace}"."#{@name}" (#{arguments})],
     %[ returns #{type} as $**PIGGLY**$],
     body,
     %[$**PIGGLY**$ language plpgsql #{strictness} #{security} #{@volatility}]].join("\n")
  end

Luke, this looks good. Beware you will need to do git pull upstream before working on this because I've made several changes to support schema-qualified types. Make sure to run rake spec before committing and submit a pull request. Thank you!
