Well, that narrows it down to a problem with the "struct group" returned
by getgrgid() ... but the code is correct according to the man page I
have here for getgrgid. You're going to have to dig further on your
own.
FWIW, I'd still wonder about whether the definition of "struct group"
seen by Postgres agrees with what libc thinks.
BTW: you wouldn't be getting into this code if the executable were owned
by the postgres user. So if you can't figure it out, a workaround
should be to change the ownership.
