TSV ? custom ?) for your bash script, then print values from bash. The commands "column" or "printf" could help you format a pretty table if really needed. > Is there any relatively simple way to do this (psql print and return > count(*))? Not in a clean way. To make psql return something else than 0, you need to trigger an error with a failing query to make it return 3 when ON_ERROR_STOP is enabled.
