Re: Using incorrect default-value type - Mailing list pgsql-general

Hello,

I have found a strange behavior in postgreSQL when adding columns with defaults of a domain type in a schema different from public. This is the example to reproduce it:

CREATE SCHEMA schema_1;

CREATE DOMAIN schema_1.text AS text;

SET search_path TO schema_1, pg_catalog;

CREATE TABLE test

(

  col1 text DEFAULT 'some value'

);

SELECT a.attname,

       pg_get_expr(d.adbin, d.adrelid) AS default

FROM pg_attribute a LEFT JOIN pg_attrdef d

           ON a.attrelid = d.adrelid AND a.attnum = d.adnum

WHERE a.attrelid = 'schema_1."test"'::regclass

                AND a.attnum > 0 

ORDER BY a.attnum;

Last query will return: 

col1     |     "'some value'::pg_catalog.text"

I don't understand why it is using "pg_catalog.text", when it should be using "schema_1.text", or in this case the query should return just "text" since the search path is using "schema_1". 

Furthermore, if I open pgAdmin and select "col1" in "test" table, SQL pane will show:

ALTER TABLE schema_1.test ALTER COLUMN col1 SET DEFAULT 'some value'::text;

but I believe, it should show:

ALTER TABLE schema_1.test ALTER COLUMN col1 SET DEFAULT 'some value'::schema_1.text;

Is this a bug or am I missing something?

Thanks,

Arturo
