This is for the benefit of running postgres under the rr debugger. When using rr signal handlers running while a syscall is active use an alternative stack. As e.g. bgworkers are started from within signal handlers, the forked backend then has a different stack base than postmaster. Previously that subsequently lead to those processes triggering spurious "stack depth limit exceeded" errors. Discussion: https://postgr.es/m/20200327182217.ubrrl32lyfhxfwk5@alap3.anarazel.de
