Prevent Postgres from automatically lower casing constraint names

This doesn’t work:

ALTER TABLE company DROP CONSTRAINT UQ_924dc2ee53aa15f1b16b4af12be;

Postgres says that this constraint doesn’t exist.

Solution

The problem is that Postgres will lowercase the constraint name. Use double quotes around the constraint name, like this:

ALTER TABLE company DROP CONSTRAINT "UQ_924dc2ee53aa15f1b16b4af12be";
