Hi All,
I have some problem with inet type on PostgreSQL-7.0 (FreeBSD
3.4-STABLE)
Table "ipaddresses"
Attribute | Type | Modifier
--------------+---------+----------------------------
sysname | text | not null
index | integer | not null
ip_addr | inet | not null
Indices: ipaddresses_ip_addr,
ipaddresses_pkey
(sysname, ip_addr) - PRIMARY KEY
View "ipaddresses_view"
Attribute | Type | Modifier
--------------+---------+----------
sysname | text |
index | integer |
ip_addr | inet |
ip_netmask | inet |
View definition: SELECT ipaddresses.sysname, ipaddresses."index",
ipv4_host(ipaddresses.ip_addr) AS ip_addr,
ipv4_netmask(ipaddresses.ip_addr) AS ip_netmask FROM ipaddresses;
ipv4_host and ipv4_netmask like original host and netmask but return
inet type ( need for ORDER )
CREATE FUNCTION ipv4_host(inet) RETURNS inet AS '
BEGIN
RETURN host($1);
END;
' LANGUAGE 'plpgsql';
CREATE FUNCTION ipv4_netmask(inet) RETURNS inet AS '
BEGIN
RETURN netmask($1);
END;
' LANGUAGE 'plpgsql';
**************************** Problem ************************
select * from ipaddresses where sysname = 'switch01.tor';
sysname | index | ip_addr
--------------+-------+------------------
switch01.tor | 1 | 127.0/8
switch01.tor | 2 | 127.0/8
switch01.tor | 3 | 209.250.155.8/27
(2 rows)
but (sysname, ip_addr) - PRIMARY KEY
127.0/8 - it's not correct output ( real 127.0.0.2/8 and 127.0.0.3/8)
select * from ipaddresses_view where sysname = 'switch01.tor';
sysname | index | ip_addr | ip_netmask
--------------+-------+---------------+-----------------
switch01.tor | 1 | 127.0.0.2 | 255.0.0.0
switch01.tor | 2 | 127.0.0.3 | 255.0.0.0
switch01.tor | 3 | 209.250.155.8 | 255.255.255.224
(2 rows)
127.0.0.2 | 255.0.0.0 and 127.0.0.3 | 255.0.0.0 - it's correct output
And of course after pg_dump and restore correct value 127.0.0.2/8 and
127.0.0.3/8 will lose
and will have problem with PRIMARY KEY - (sysname, ip_addr).
