Looking forward to it.

Hi Nathan!

Sorry for the delay, I was busy with other professional as well as personal activities.

I made all the changes you suggested. I removed the variables and started using
views "pg_stat_ssl" and "pg_stat_gssapi". I handled the PostgreSQL versioning regarding the views used.

Here's a brief demonstration of the result:

[postgres(at)localhost ~]$ /home/pgsql-17devel/bin/psql -E -x -p 5433

psql (17devel)
Type "help" for help.

postgres=# \conninfo+
