Question

Here’s how I can do it when MySQL is the backend,

    cursor.execute('show tables')
    rows = cursor.fetchall()
    for row in rows:
        cursor.execute('drop table %s; ' % row[0]) 

But how can I do it when postgresql is the backend?

Answer 1

You can use select * from pg_tables; get get a list of tables, although you probably want to exclude where schemaname <> 'pg_catalog'…

Based on another one of your recent questions, if you’re trying to just drop all your django stuff, but don’t have permission to drop the DB, can you just DROP the SCHEMA that Django has everything in?

Also on your drop, use CASCADE.

EDIT: Can you select * from information_schema.tables; ?

EDIT: Your column should be row[2] instead of row[0] and you need to specify which schema to look at with a WHERE schemaname = 'my_django_schema_here' clause.

EDIT: Or just SELECT table_name from pg_tables where schemaname = 'my_django_schema_here'; and row[0]
