Crea un database Postgres usando Python

Nessuna transazione viene avviata quando viene emesso il comando e non è richiesto commit() o rollback().

import psycopg2
from psycopg2 import sql
from psycopg2.extensions import ISOLATION_LEVEL_AUTOCOMMIT # <-- ADD THIS LINE

con = psycopg2.connect(dbname='postgres',
      user=self.user_name, host='',
      password=self.password)

con.set_isolation_level(ISOLATION_LEVEL_AUTOCOMMIT) # <-- ADD THIS LINE

cur = con.cursor()

# Use the psycopg2.sql module instead of string concatenation 
# in order to avoid sql injection attacs.
cur.execute(sql.SQL("CREATE DATABASE {}").format(
        sql.Identifier(self.db_name))
    )
