EOL for 7.4?

We had a discussion back in July about our maintenance policy and the
upshot of that discussion was that there were relatively few
objections to dropping support for 7.4 - I believe Andrew Dunstan was
the only one who spoke against it, and it wasn't clear how strenuous
his objections were - but there were objections even to setting an
end-of-life date for any subsequent release.  However, we never really
took any action based on that conversation.  Maybe it's time?

Part of the reason I suggest this is because it seems that not much
gets patched back that far any more.  AFAICT, committers basically
stop back-patching at the point where it becomes an inconvenience, and
most of the time that happens before you get that far back.  As a
result, while 7.4 is technically supported, it's not really all that
supported.

We are also very close to six years from the original release, if
that's a magic number for anyone.
