Hmmm?  No way - see below.

I will search the archives, but I'll explain my thoughts here a well.

Well, what's the problem with appending a number - that's how index names
get generated.

This is my horrible schema that forced me to abandon using SERIAL in favour
of explicit CREATE SEQUENCE statements:

BEGIN;

-- Categories of foods
CREATE TABLE medidiets_categories_foods (category_id SERIAL,description varchar(255) NOT NULL,PRIMARY KEY(category_id)
);

-- Categories of recipes
CREATE TABLE medidiets_categories_rec (category_id SERIAL,description varchar(255) NOT NULL,PRIMARY KEY(category_id)
);

COMMIT;

Both of these SERIALs are given the same name - it's a real pain.
