Previously we did this in PostmasterMain() and InitPostmasterChild(), which meant that stack depth checking was disabled in non-postmaster server processes, for instance in single-user mode. That seems like a fairly bad idea, since there's no a-priori restriction on the complexity of queries we will run in single-user mode. Moreover, this led to not having quite the same stack depth limit in all processes, which likely has no real-world effect but it offends my inner neatnik. Setting the depth in main() guarantees that check_stack_depth() is armed and has a consistent interpretation of stack depth in all forms of server processes. While at it, move the code associated with checking the stack depth out of tcop/postgres.c (which was never a great home for it) into a new file src/backend/utils/misc/stack_depth.c.
