Reset the conversion procs when extending the Database
object, so it will pick up the inet/cidr converter. Also, extend the datasets with support for literalizing the IPAddr types.

# File lib/sequel/extensions/pg_inet.rb 67 def bound_variable_arg(arg, conn) 68 case arg 69 when IPAddr 70 "#{arg.to_s}/#{arg.instance_variable_get(:@mask_addr).to_s(2).count('1')}" 71 else 72 super 73 end 74 end
Convert an IPAddr arg to a string. Probably not necessary, but done for safety.

# File lib/sequel/extensions/pg_inet.rb 79 def schema_column_type(db_type) 80 case db_type 81 when 'inet', 'cidr' 82 :ipaddr 83 else 84 super 85 end 86 end
Make the column type detection recognize the inet and cidr types.

Set the :ruby_default value if the default value is recognized as an ip address.

Typecast the given value to an IPAddr object.
