# The LooserTypecasting extension loosens the default database typecasting
# for the following types:
#
# :float :: use to_f instead of Float()
# :integer :: use to_i instead of Integer()
# :decimal :: use 0.0 for unsupported strings
# :string :: silently allow hash and array conversion to string
#
# To load the extension into the database:
