Interesting - 0xC0000409 means STACK_BUFFER_OVERRUN... The only case
I've seen that happen on connection startup is, as usual, with broken
antivirus/antispyware on the machine. If you have any such product
installed, try uninstalling it (not just disabling it) and see if the
problem goes away.

The error occurred on the server, not the client if you got that
message. The question is what you did on the server when it happened.
If it happened connection, then I would look into things like anything
you have configured in shared_preload_libraries for example.

Not that I know of, but it's always a possible side-effect from
something else - so it's always worth applying the latest patches.
