We can also free()/pfree() userDoption in postgres.c and bootstrap.c?

Since userDoption typically uses only a small amount of memory, I'm not sure
this patch provides much practical benefit from a memory-leak perspective.
So I don't think it needs to be backpatched to the stable branches.

OTOH, if it helps keep Valgrind quiet for userDoption, I may be ok with
applying it to master.
