Bug reference: 18464
Logged by: Rémi Cura
Email address: remi.cura@gmail.com
PostgreSQL version: 14.10
Operating system: Linux
Description:
I have a SQL function that I defined myself. Let's call it MyFunction().
I use MyFunction in generated columns of 2 distinct tables.
Whe trying to delete MyFunction, the DB correctly raises an error.
However, when I `CREATE OR REPLACE` this existing function in place, the DB
silently drop all the generated columns depending on this function.
This is not the expected behavior.
I should get either an error, or no columns should be dropped.
if they are dropped, I should get at the very least a warning.
This is pretty major: having columns disappear magically on prod dbs is not
what postgres usually do.
