While in preview, there are a few [limitations to keep in mind](/guides/postgres-postgresql-postgres-version-support#postgres-18-support).

To learn more about the new features and improvements in Postgres 18:

- Read our blog post: [Postgres 18 Is Out: Try it on Neon](https://neon.com/blog/postgres-18)

## Monitor Postgres network traffic with Elephantshark

We’ve released **Elephantshark**, an open-source Ruby script from Neon for monitoring Postgres network traffic.

Elephantshark sits between Postgres clients and servers, decrypting and re-encrypting SSL/TLS traffic while logging protocol messages. It works with all Postgres-protocol traffic, not just Neon databases. It can also generate `SSLKEYLOGFILE` entries for Wireshark.

- [Get Elephantshark on GitHub](https://github.com/neondatabase-labs/elephantshark)
