Thread: BUG #4277: Feature request inet type cast numeric values

The following bug has been logged online:

Bug reference:      4277
Logged by:          x
Email address:      noreply@postgresql.org
PostgreSQL version: n/a
Operating system:   n/a
Description:        Feature request inet type cast numeric values
Details:

SELECT inet 2130706433;

Should return:
?column?
--------
127.0.0.1

This would emulate the functionality:
CREATE OR REPLACE FUNCTION inet_ntoa(bigint) RETURNS text AS '
SELECT (($1>>24) & 255::int8) || ''.'' ||
(($1>>16) & 255::int8) || ''.'' ||
(($1>>8) & 255::int8) || ''.'' ||
($1 & 255::int8) as result
'
LANGUAGE 'SQL';

You can create the cast yourself if you want to, see CREATE CAST.

The proposed cast seems rather inappropriate in an IPv6 world anyway.
If you want IPv4-only functionality, I think the inet4 type on
pgfoundry has this behavior already.
