Here's the real problem --- why are you getting a SIGBUS while trying to
load the pltcl handler function? I suspect something broken in Tcl's
shared library, but dunno what. You should be getting a core file from
the crashed process --- can you get a stack trace from it with gdb?

This is evidently happening during attempted restart after the backend
crash. I suspect it is a matter of the OS not having released the old
memory segment yet, together with the SHMMAX limit being too tight to
allow two such segments to exist concurrently. Are you able to start
the server by hand immediately afterwards, or a few seconds afterwards?
Or do you have to reboot before it will restart?
