7.4 defaulting to ipv6 ?

[Kaare Rasmussen]

Sorry if this is obvious to you, but it's not obvious to me.

In 7.4 this

psql -h 127.0.0.1 test and
psql -h localhost test

will be authenticated as ipv6 addresses. As long as you know, it's OK, but is
this intentional?

This will be clearer in 7.4beta3. We will accept 127.0.0.1 properly.

Only if your libc and/or kernel preferentially treats them as ipv6.

CVS tip contains a fix to allow ipv4 addresses in pg_hba.conf to match
ipv4-mapped-to-v6 ipv6 connections; this should allow people to continue
believing they are using ipv4 even when their system is mapping to v6.

TIP 2: you can get off all lists at once with the unregister command
(send "unregister YourEmailAddressHere" to ma*******@postgresql.org)
