I don't see that here on RHEL8, and https://coverage.postgresql.org seems to be working so it doesn't fail on Alvaro's Debian setup either. What configure options are you using? Does "nm -u" report "exit" being referenced from any *.o in libpq, or from any *_shlib.o in src/port/ or src/common/ ? regards, tom lane
