I still have this problem. I have a wallboard that rotates graphs, and when I render a graph that isn't being shown, it stacks the legends ontop of each other.

Doing something approximate could be better (and would be much faster) ```SELECT n_live_tup FROM pg_stat_user_tables WHERE relname='tablename';``` using `SELECT COUNT(1)` from a table causes it to do a full scan....

I guess my preference was to prevent anything that requires escaping when accessing files in shell, which included `;`, `$`, etc

This happens in all the waiters, I presume. I was pulling my hair out trying to figure out why my ECS `waitUntilTasksRunning` and `waitUntilTasksStopped` were hanging for no reason.
