Bug reference:      17095
Logged by:          Vitali Lovich
Email address:      vlovich+github@gmail.com
PostgreSQL version: 14beta2
Operating system:   Arch Linux
Description:

When I run configure with -fsanitize=address (using clang 13 at revision
d3676d4b666ead794fc58bbc7e07aa406dcf487a), it errors out because
`thread_test.c` is violating thread safety.

Specifically it complains about the access of errno2_set, errno1_set,
thread1_done, & thread2_done being read/modified from multiple threads
without any kind of synchronization. AFAICT these TSAN errors are correct.
