This seems like a bad use of a stored procedure. Why wouldn't you spin up
40 clients with a table name and run it across 40 connections? But also, I
don't like loops in stored procedures. Working with loops in a set based
system hurts me but it's personal preference.
Like, I could write this in py

Applications do this kind of thing all the time, very successfully; it
was just that the loop was in the application rather than in the procedure.
High commit rates happen all the time, and they don't break PostgreSQL.
For example, an IoT app

This is an over-generalization. There are many use-cases for this (if there
were not, procedures wouldn't have been nearly as important a feature).
For example, if you are processi
