The term “proxy” refers to their role as an intermediary for the traffic between an application client and an application server.

The main goal of the PostgreSQL filter is to capture runtime statistics while remaining completely transparent to the database server.
As a result, YugabyteDB is able to leverage the PostgreSQL filter from Envoy without any modifications whatsoever.
As we can see above, we have configured an Envoy listener on port 1999 that has a filter chain with two filters, namely PostgreSQL and TCP.
