psql is a great tool. Oftentimes, output of the particular command in psql is too big to fit on one screen, hence outputs are wrapped to fit in one screen which becomes output unreadable. To custommize command output in readable format we have system variable called PAGER. If its on linux, I can simply set PAGER variable with LESS command + options to view command ouptut in readable format.
In our regular DBA monitoring, we will be using so many combination of pg_catalog queries to reteive information like <IDLE> in transaction , waiting queries, No. of connections, etc. Most of the DBA’s, create views to cut short big combination queries and keep handy for later use per requirement.
PostgreSQL, provides a startup file(.psqlrc) which executes before connecting to the database when using with psql utility. Using .psqlrc file you can place all your important queries with one word alias by ‘\set’ command and execute it in psql terminal instead of typing big queries.
