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
