Is it possible/safe to compile the latest version of pg_autovacuum, and use
it with a 7.2.4 postmaster?
I know the better solution would be to upgrade everything, but that involves
a lot of work which we've managed to put off for a long time already, and
autovacuum is pretty much the only feature we really need immediately.

As far as I know, yes. I have tested pg_autovacuum against 7.3.x and
that work fine.
Since pg_autovacuum is just a standard client app that looks at stats
collector info to make decisions about when to vacuum, it should work.
I think there may be been some stats collector bugs that have been fixed
since 7.2.x, but for the most part it should work just fine.
Please post your results as it might be useful to know if it works.

Actually, no, it doesn't.
pg_autovacuum will "crap out" if pointed at a 7.2.x instance. It
seems most likely that the cause is some changes to the pg_ tables
between the versions; I haven't found the Round Tuits to dig deeply
into it. I no longer have any 7.2 instances I am concerned about for
autovacuum, so I in a sense "don't care" anymore...
If I had the "round tuits," what I'd rather do is to create a daemon,
probably in Perl/Python, that is up to the task of managing a whole
cluster of backends... That is VERY different from the common desire
for something integrated tightly into the back end; I can foresee
value to both approaches...

I've hit something of a snag.
Problem:
In a DSP application we have data profiles with a varying number of points.
We have a number of Discrete Fourier transforms that are optimised for a
specific number of points. Currently, any client of these DFT classes must
switch on the number of points in the profile and instanciate the correct
DFT algorithm.

Here's what I want do:
Have a main daemon which starts up several threads in a Boss-Queue structure.
From those threads, I want them all to sit and watch a queue. Once an entry
goes into the queue, grab it and run a system command.
Now I want to make sure that system command doesn't hang forever, so I need some
way to kill the command and have the worker thread go back to work waiting for
another queue entry.
