How portable is getrusage()? Could the postmaster issue that 
frequently for RUSAGE_CHILDREN and leave the result somewhere in the 
shared memory for whoever is concerned?

SVr4, BSD4.3, SUS2 and POSIX1003.1, I believe.

I also believe there is a M$ dll available that gives that functionality 
(psapi.dll).
Remains the question when it is updated, the manpage doesn't tell. If 
the RUSAGE_CHILDREN information is updated only when the child exits, 
each backend has to do it.
