Bug reference:      2274

Description:        Error in 'CREATE DOMAIN'  SQL command in dump file
Details:

I have created domain 'address_period_tsi':
SET search_path = public, pg_catalog;

CREATE TYPE tsinterval
  (
    INPUT=tsinterval_in,
    OUTPUT=tsinterval_out,
    DEFAULT='',
    INTERNALLENGTH=32,
    ALIGNMENT=int4,
    STORAGE=PLAIN
  );

SET search_path = kladr, pg_catalog;

CREATE DOMAIN address_period_tsi
  AS public.tsinterval
  NOT NULL
  DEFAULT '(-infinity..infinity)';

I have create and load dump file 'test.dump':
pg_dump -U postgres test >test.dump

psql -U postgres -f test.dump -d test

psql:test.dump:415: ERROR:  type "tsinterval" does not exist

In dump file:
CREATE DOMAIN address_period_tsi
  AS public.tsinterval
  NOT NULL
  DEFAULT '(-infinity..infinity)'::tsinterval;

Some result if i have create domain:
CREATE DOMAIN address_period_tsi
  AS public.tsinterval
  NOT NULL
  DEFAULT '(-infinity..infinity)'::tsinterval;

OR:
CREATE DOMAIN address_period_tsi
  AS public.tsinterval
  NOT NULL
  DEFAULT '(-infinity..infinity)'::public.tsinterval;

I can't duplicate this --- for me, pg_dump produces

CREATE DOMAIN address_period_tsi AS public.tsinterval NOT NULL DEFAULT '(-infinity..infinity)'::public.tsinterval;

which reloads just fine.  Could you provide a more complete example?

Thanks for the test case.  The reason I missed it is that the bug turns
out to depend on the schema path at the time you create the domain, not
only on what pg_dump does.  (It's effectively dumping the default
according to the creation-time search path, rather than the one that
pg_dump wants to use.)  I've committed a fix for 8.1.4.  In the meantime
you can work around it by setting the search path the way pg_dump wants
at the time you create the domain, ie,

    set search_path = my_schema, pg_catalog;

    create domain ... default 'foo'::public.ltree;
