How to show Rails ActiveRecord query time in Heroku pry rails console?

When I run an ActiveRecord query in my local console, I am shown both how long the query took to run (in ms) and the raw SQL that was generated from my ActiveRecord code. For example:

$ rails c
Running via Spring preloader in process 92420
Loading development environment (Rails 6.1.3)
[1] pry(main)> TableName.count
   (26336.8ms)  SELECT COUNT(*) FROM "table_names"
=> 10005457

But when I run the same query in a Heroku rails console, I don't see the query time or SQL, just the result. Example:

$ heroku run rails c
Running rails c on ⬢ app-name... up, run.9115 (Free)
Loading production environment (Rails 6.1.3)
[1] pry(main)> TableName.count
=> 10005457

If it's relevant, I have gem 'pry-byebug' and gem 'pry-rails' installed via my Gemfile (not in the development group). I'm also using PostgreSQL as my database.

Whether to display query time and SQL depends on Log Levels.

It displays when the log level is :debug or corresponding number 0.

You could check config.log_level in config/environments/production.rb.

If it's :debug, then it might be Heroku has changed log level somehow.

You could check the log level in Hereku console by Rails.logger.level.

And set log level to :debug by Rails.logger.level = :debug.
