I suppose things are a bit more complicated than that.  We once has a
brief suspicion that it could be related to Sun's tmpfs file system that
/tmp often resides on, but I don't think this turned out to be the case.

Indeed.  A while ago I looked around and found at least two packages (INN
and Postfix) that had similar-sounding problems.  In fact, one of the two
ended up disabling it with the words "more trouble than it's worth".

You could argue that X and KDE and what else should be broken as well.
This is a good question.  It could perhaps be related to a buffer problem,
under the assumption that X usually passes small amounts of data through
the pipe, whereas PostgreSQL can pass megabytes in a very short time.
(Don't know what INN and Postfix would want to do with a local socket.)


The bottom line here is that the switch from local sockets to TCP/IP
invariably fixes the identical failure pattern.  Make of that what you
will.
