To check this, I updated my laptop (still on Catalina 10.15.7) to latest
Xcode, 12.2 (12B45b), from 12.0 --- and behold, I could duplicate it:
Undefined symbols for architecture x86_64:
"___darwin_check_fd_set_overflow", referenced from:
_ClientAuthentication in auth.o
_pgstat_init in pgstat.o
_ServerLoop in postmaster.o
ld: symbol(s) not found for architecture x86_64
However ... it then occurred to me to blow away my ccache and accache,
and after rebuilding from scratch, everything's fine. So, are you
using ccache?
