Re: CREATE TABLE & composite type

Thanks Adrian
My concern is that this will have to execute all code in the function only
to return a empty dataset - his may be ineffective.
A possible workaround will be to have a dedicated param which will determine
whether or not to exit at the start of the function.

I also just realised that a possible workaround will be to create tables
instead of composite types ("Whenever you create a table, a composite type
is also automatically created").

I.e. instead of doing:
CREATE TYPE inventory_item AS ( name text, supplier_id integer, price
numeric );

create an actual table (which will never be used):
CREATE TABLE inventory_item AS ( name text, supplier_id integer, price
numeric );

However, having unused tables in the schema kind of goes against the
grain...
