How to I reset the statistics for pg:outliers?

Issue

I've made some changes to how I access my Postgres database and now the resulting pg:outliers statistics are stale.

Resolution

You can reset the pg_stat_statements directly in a psql console or you can one-line it with the Heroku CLI like so: heroku pg:psql <database> -a <app name> -c "SELECT pg_stat_statements_reset();".
