Uh, it was my attempt to have both good CI tests (running in a non-interactive mode) and the main, interactive mode for humans.

An unfinished attempt – t1 doesn't offer any recommendations, the work is unfinished. It only shows the main performance configuration params, and then you can use something like https://pgtune.leopard.in.ua/ to perform tuning (very, very basic, of course).

I'm thinking about what to do with it, thanks for the bug report @msdnchina! Somehow this error is not easy to notice.

To get rid of it right now, please add this to ~/.psqlrc:

\set postgres_dba_interactive_mode false
