Suricata

We have PostgreSQL/pgsql protocol logging - it is great to have it in the SIEM and doing visualizations with it.
While i as doing that a few thing made an impression on me that we could add key words in order to trigger an alert (not just have it as protocol data being logged).

We could use some keywords for the below:

pgsql.request.protocol_version
pgsql.response.parameter_status.is_superuser
pgsql.request.startup_parameters.user
pgsql.request.startup_parameters.optional_parameters.database
pgsql.response.authentication_md5_password 

The idea is to highlight weak or clear text password , miscconfiguration also match on a field - if it exists or if it has specific content.
This is very valuable especially from the perspective if the communication is North/South.
Screenshot attached is simple list form Kibana for reference.

Would be great if this can be done in Suricata 8 , not just 9.
