With the update_process_title parameter set to off some PostgreSQL
processes still change their ps title to a different name than the
default. I appreciate this setting came about for performance reasons
which the logger, wal writer, autovacuum, and stats collector would
not have but I actually require the default and patched
init_ps_display() to skip changing the name.
It just surprised me that the titles still changed a single time.
I (stupidly?) installed PostgreSQL into a hostile environment which
didn't like this and decided to kill the processes as a result.
Unfortunately, I cannot change the environment.
