Add ipv6 address parsing support to 'inet' and 'cidr' data types.
Regression tests for IPv6 operations added.
Documentation updated to document IPv6 bits.
Stop treating IPv4 as an "unsigned int" and IPv6 as an array of
characters. Instead, always use the array of characters so we
can have one function fits all. This makes bitncmp(), addressOK(),
and several other functions "just work" on both address families.
add family() function which returns integer 4 or 6 for IPv4 or
IPv6. (See examples below) Note that to add this new function
you will need to dump/initdb/reload or find the correct magic
to add the function to the postgresql function catalogs.
IPv4 addresses always sort before IPv6.
On disk we use AF_INET for IPv4, and AF_INET+1 for IPv6 addresses.
This prevents the need for a dump and reload, but lets IPv6 parsing
work on machines without AF_INET6.
To select all IPv4 addresses from a table:
select * from foo where family(addr) = 4 ...
Order by and other bits should all work.
