Adding dict object to postgresql

So I am using psycopg2 on Python3.5 to insert some data into a postgresql database. What I would like to do is have two columns that are strings and have the last column just be a dict object. I don't need to search the dict, just be able to pull it out of the database and use it.

so for instance:

uuid = "testName"
otherString = ""
dict = {'id':'122','name':'test','number':'444-444-4444'}

# add code here to store two strings and dict to postgresql

cur.execute('''SELECT dict FROM table where uuid = %s''', 'testName')
newDict = cur.fetchone()
print(newDict['number'])

Is this possible, and if so how would I go about doing this?
