Hi, so libpq has this line in its Makefile https://github.com/postgres/postgres/blob/6ee26c6a4bafabbd22a85f575d2446fd5ec6ad0d/src/interfaces/libpq/Makefile#L116 which checks that libpq does not use any "exit" functions. With ThreadSanitizer it triggers on function `__tsan_func_exit` which is used to record returns from functions. Should it be added to exclusion list here?
Error looks like this, just in case: ... rm -f libpq.so ln -s libpq.so.5.15 libpq.so libpq.so.5.15: U __tsan_func_exit libpq must not be calling any function which invokes exit make: *** [Makefile:121: libpq-refs-stamp] Error 1
