Using PostgreSQL / pgAdminIII, is it possible to send command line commands to PostgreSQL via the UI? Put another way: how can I access the command line via the pgAdminIII?
As I am coming up to speed on pgAdminIII, occasionally it seems like it would be useful. Ex: I search for a solution to an issue, but all I find is a solution that involves the command line, not the pgAdminIII UI.
Maybe I am not understanding something more fundamental here, or maybe I am not using the proper terminology, but for example in this link Jay Taylor's answer seems to use the command line commands I am referring to: https://stackoverflow.com/questions/760210/how-do-you-create-a-read-only-user-in-postgresql
In this link Bruno's answer uses them: https://stackoverflow.com/questions/20775462/cant-grant-user-privileges-to-postgresql-database-for-a-rails-app
In this link there are several references to them: https://jamie.curle.io/creating-a-read-only-user-in-postgres
Explicitly, from the last link above, how would I send something like this to PostgreSQL/the server from pgAdminIII (not that I actually want to):
pg_dump -O -Fc --format=t productiondb -U backup_user -h localhost
