Technical summary

Patroni primary_conninfo handling needs to account for PostgreSQL 17 sslnegotiation support.

Include or preserve sslnegotiation in primary_conninfo only when the PostgreSQL version supports that connection parameter.

This issue is version-gated around PostgreSQL 17, so older server versions should keep existing primary_conninfo behavior.

The snippet uses native project logic; primary_conninfo parameters from DCS are normalized before Patroni writes recovery settings. The helper result is consumed directly by the patched code path.

After applying the patch, keep the import smoke test for the affected package:

python3 -c "import patroni; print('smoke test OK')"
