could not receive data from client: Connection reset by peer

[gitmalong]

Anyone facing those errors in postgres 16 logs?

It happens when I am doing many concurrent operations (bulk insert, and 500 cons busy with single row reads). Lowering my through params make this issue not appear.

Rust app logs just show

 Error: Connection Error: error communicating with database: Connection reset by peer (os error 54)

Caused by:
