Info on error `Connection to client lost`

Hi Pg team,

What are the scenarios under which we see `FATAL: Connection to client
lost`.
One case I could think of is client application closes connection abruptly
incase of exceptions(for example: column x is not found).
Can you please share what could be other scenarios we see this error.

Thanks in advance.

Thanks,
Mahendrakar.

As Larry said, the most probable cause is a network problem.

The driver could also have a short default timeout, but it is
difficult to say  more, as you did not provide with any context, such
as, does it take place on the same machine or is it a machine to
machine link, which language was used to write the app, which driver is
in use, etc.
