In AutoVacWorkerMain, I am reading the following:
* Currently, we don't pay attention to postgresql.conf changes that
* happen during a single daemon iteration, so we can ignore SIGHUP.
*/
pqsignal(SIGHUP, SIG_IGN);
So a worker does not see changes in postgresql.conf once it is run and
processes a database, no? The launcher does run ProcessConfigFile()
when SIGHUP shows up though.
