All modes complete within seconds with the final "database system is
shut down" message, unlike the hang you're experiencing.
The patch only moves __ubsan_default_options() to a separate
compilation unit to avoid TSan initialization issues during startup.
It doesn't modify any shutdown logic or signal handling code.
My Environment: Ubuntu 24.04.1, clang 18, PostgreSQL 17.2.
Great! My OS is macOS 15.6.1. I will continue to test to confirm if
there are any other issues. If so, I will create a separate patch.
