monetdbe.exceptions.OperationalError: CREATE FUNCTION: name 'afunkyfunc' (double) already in use

ie the current monetdbe (0.11) has an issue with function creation, I seem to remember I fixed something for this (on default this is fixed, not sure how the status on jul branch is).

import monetdbe
import os
database = '/tmp/test.mdbe'
# Removes the database if it already exists
if os.path.exists(database):
    os.system(f'rm -rf {database}')
with monetdbe.connect(database) as conn:
    #conn.set_autocommit(True)
    cursor = conn.cursor()
    q = "create function afunkyfunc(a double) returns double begin return a/2; end"
    res = cursor.execute(q)
    res = cursor.execute("select afunkyfunc(1.0);")
    print(cursor.fetchone()[0])

is the test I used
