Remove usage of potentially unsafe SQL constructs
Looks like https://git.csclub.uwaterloo.ca/public/pyceo/src/branch/master/ceod/db/MySQLService.py#L47 and the PostgreSQL equivalent are using f strings to format the queries they execute.
As far as I'm aware, this doesn't protect against SQL injection, and although I know everyone in the CSC are good, machine usage policy following people, it should probably be changed to use the safer constructs outlined here: https://www.psycopg.org/docs/usage.html#passing-parameters-to-sql-queries and the MySQL equivalents.
Should just be contained in
Actually this isn't really user facing, and probably isn't called with user-facing code so it's probably not an issue, but it's a pretty straightforward fix AFAIK.
Deleting a branch is permanent. It CANNOT be undone. Continue?
