Обсуждение: No way to list DDL for a new type

Hi,
I created a new type as follows:
CREATE TYPE compfoo AS (f1 int, f2 text);

Now I need the DDL which postgres used to create this type.

Thanks.

With Regards,

Huh, what do you mean? That CREATE TYPE statement is DDL.

Anyway, this doesn't sound like a bug. Please use the appropriate
mailing list, probably pgsql-general. This list is for bug reports only.

I think what the OP was asking was how to reverse engineer the DDL out
of the database for an already created type (but you're right, this is
not a bug).  in psql, the create type source sql is not displayed like
it is for views for example.

There are a couple of ways to do this:
*) pg_dump -s and examine the output
*) fire up pgadmin, browse types folder-- pgadmin shows source ddl for
all database objects

Also, composite types (CREATE TYPE AS), are trivially reverse
engineered from the column lists.  Non composite types are a little
more complicated.

side thought -- it would be nice for pg_restore to be able to extract
more specific objects out of the custom format dump than what it
currently allows...types for example.
