It looks to me like the fact that the .lock file is created is only
documented in src/backend/utils/init/miscinit.c , and even there the
reason why (what you wrote above) isn't mentioned. Seems like noting
this file is created in the unix_socket_directory entry of the docs, and
the rationale for why in the source code, would make a useful
improvement. Anybody want to write a little documentation patch?
