In mysql, INFORMATION_SCHEMA.TABLES has all the tables of all databases, not
just the database you're connected to.
This is probably why you get duplicates. To select only the tables of the
current database, which is what SHOW TABLES does, you could add this clause:
In postgresql, the schema does not equate the database; it's a namespace
inside a database, so the clause above has to be different. Assuming the db
doesn't use multiple schemas, it could be:
... AND table_schema='public'
