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.
