Description:

Good morning,

Last October 2nd the postgresql service shut down the database
unexpectedly.

We only have this entry in the log file. Please, is there any way to
investigate the problem with so little information?

sqlstate: 00000 > LOG:  received immediate shutdown request

Thank you very much

That is a commanded shutdown: something sent the postmaster process
a SIGQUIT signal.  The cause is very unlikely to be within Postgres
itself.  You should be thinking in terms of operator error or a
misbehaving administrative script.
