Hi, I wonder if it'd make sense to allow a signal to trigger a memory context dump? I and others more than once had the need to examine memory usage on production systems and using gdb isn't always realistic. I wonder if we could install a signal handler for some unused signal (e.g. SIGPWR) to dump memory. I'd also considered adding a SQL function that uses the SIGUSR1 signal multiplexing for the purpose but that's not necessarily nice if you have to investigate while SQL access isn't yet possible. There's also the problem that not all possibly interesting processes use the sigusr1 signal multiplexing.
