Re: Time to drop plpython2?

Hi,

Thanks to some more buildfarm animal updates things are looking better. I
think there's now only three owners that haven't updated their animals
successfully. One of which I hadn't yet pinged (chipmunk / Heikki), done now.

There's snapper ("pgbf [ a t ] twiska.com"), and there's Mark Wong's large
menagerie. Mark said yesterday that he's working on updating.


There's one further failure, but the symptoms are quite different. I've also
pinged its owner. I think it's a problem on the system, rather than our side,
but less certain than with the other cases:

This is a 64bit host, targetting 32bit "CFLAGS' => '-m32'. However it linked
successfully against python 2.
