This is better asked on the pgsql-general mailing list, but the short
answer is that you have to look at your search_path as well. Since you just
created schema_1, and public is in your search_path, a plain seq_xx_yy is
the one from the public schema. To see the fully-qualified name, run:
SET search_path = pg_catalog;
before issuing your select from information_schema.columns
Cheers,
Greg
