NPE in PgDecoder if a notice is raised while no query is being executed

trafficstars

See #1442

This may happen if the connection is used by a PgSubscriber.

no test ?

@vietj I searched the web for cases when the server would raise a notice/error not related to a client request, but I couldn't find any. Have you encountered this case yourself before?

[vietj]

I think it can be reproduced using a proxy, we have similar tests like that

[vietj]

you can look at testDisconnectAbruptlyDuringStartup

I think you misunderstood my comment, the problem is not to test re-connection, the problem is to force the PostgreSQL server to raise a notice message while there are no inflight commands on the connection.

Afaiu this is not the case in testDisconnectAbruptlyDuringStartup

[vietj]

yes, Im saying to use the proxy server to create a fake message to be sent to the client using it
