This patch gets us out from under the Unix limitation of two user-defined signal types. We already had done something similar for signals directed to the postmaster process; this adds multiplexing for signals directed to backends and auxiliary processes (so long as they're connected to shared memory). As proof of concept, replace the former usage of SIGUSR1 and SIGUSR2 for backends with use of the multiplexing mechanism. There are still some hard-wired definitions of SIGUSR1 and SIGUSR2 for other process types, but getting rid of those doesn't seem interesting at the moment. Fujii Masao
