Hi all,

I am receiving the following error in postgres log:

FATAL,57P01,"terminating connection due to administrator command"...

From application side, they are getting following error:

Psqlexception: FATAL,: terminating connection due to administrator command.

How to resolve this?

Tell your administrator not to terminate connections.

No, some application has called pg_terminate_backend() function or the server was shut down.

Concretely, this indicates that something sent the server process
a SIGTERM signal.  At least within Postgres, that can only come
from pg_terminate_backend() or the postmaster sending it because
it was sent a SIGINT signal to do a fast shutdown.

So, if you weren't doing this intentionally, you need to look
for an external source of those signals.

A common newbie mistake that could lead to this is launching the
postmaster by hand, or in a shell script, in a way that doesn't
dissociate it from your terminal session.  In that case typing
control-C or ending the session would deliver one of these
signals.  Make sure your postmaster start script (a) uses nohup
and (b) redirects all three of postmaster's stdin, stdout, and
stderr away from the terminal.

Could be something else too, but in the end you've got something
signaling the server that you don't want.
