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. Regards, -- Fujii Masao
