Is this an attempt to create new worker?
No records (presumably) in pg_stat_activity, only "invalid length of
startup packet" after closing telnet session.
To be expected. There's a bunch of startup stuff that happens before a
backend shows up in pg_stat_activity. See BackendStartup() for details.
In particular, BackendInitialize() is what collects the startup packet
from the port before calling BackendRun() which calls PostgresMain()
which is what finally registers the backend in the proc array.
