hi. Can you check my first email about "a" versus "the" and "pg_stat_activity".
also: "including the `\bind` command, which allows users to execute parameterized queries (e.g `SELECT $1 + $2`) then use `\bind` to substitute the variables." The example actually is very hard to reproduce. (it's not that super intuitive). fail case: test16-# SELECT $1 + $2 \bind 1 2 test16-# ; a better example would be (e.g `SELECT $1 , $2`). The semicolon still needed to be in the next line.
