Error: This socket is closed.

[strk]

An exception is thrown on client.query() if the connection was closed due to stream error. See #537 (comment)

I guess an event should be raised instead...

Can you give an example of how to reproduce this?

[strk]

untested:

• call connect, wait for "onConnect" event.
• kill the backend (pg_ctl stop)
• invoke an arbitrary query using client.query(), wait for "onError" event

The event is never sent, an exception is thrown by client.query instead
