Updated my code to this:

curr.pgsql.execute('''
INSERT INTO my_table(name, age)
SELECT %s, %s
WHERE NOT EXISTS(SELECT name FROM my_table WHERE name= name)
''', ('Scott', 23))

If I remove SELECT statement, I will get an error message: error : 
psycopg2.ProgrammingError: syntax error at or near "WHERE"
LINE 12:                         WHERE NOT EXISTS

Trying to coordinate with Lead Dev about adding Index On The Fly

I tried to figure how to make this work and could not, so I led you down a 
false path.

What I tried is
'''INSERT INTO my_table(name, age)
SELECT %s, %s,
WHERE NOT EXISTS(SELECT name FROM my_table WHERE name=%s)''', ('Scott', 23, 
'Scott'))

How about:

'''INSERT INTO my_table(name, age)
VALUES( %s, %s)
WHERE NOT EXISTS(SELECT name FROM my_table WHERE name=%s)''', ('Scott', 23, 
'Scott'))
