Checking if a postgresql table exists under python (and probably Psycopg2)

Question

How can I determine if a table exists using the Psycopg2 Python library? I want a true or false boolean.

Answer 1

#!/usr/bin/python
# -*- coding: utf-8 -*-

import psycopg2
import sys


con = None

try:

    con = psycopg2.connect(database='testdb', user='janbodnar') 
    cur = con.cursor()
    cur.execute('SELECT 1 from mytable')          
    ver = cur.fetchone()
    print ver    //здесь наш код при успехе


except psycopg2.DatabaseError, e:
    print 'Error %s' % e    
    sys.exit(1)


finally:

    if con:
        con.close()
