Once you've created schemas for administration purposes, you'll want to move existing objects to keep things tidy.
To move one table from its current schema to a new schema, use the following:
ALTER TABLE cust SET SCHEMA anotherschema;
If you want to move all objects, you might consider just renaming the schema itself using the following query:
ALTER SCHEMA existingschema RENAME TO anotherschema;
This only works if another schema with that name does not already exist.
Otherwise, you'll need to run
ALTER TABLE for each table you would like to move. You can use the recipe for performing the same action on many tables to achieve that.
Views, sequences, functions, aggregates, and domains can also be moved ...
