Hi,

Why does
ALTER EXTENSION name OWNER TO new_owner;
not exist?

I have a bunch of extensions that were installed by a role that I want
to drop. So I thought I would do like I do for other object types:
ALTER <object_type> name OWNER TO new_owner;

But that doesn't exist for extensions. I also can't drop the extension
and recreate it because other objects depend on it.

What can I do?

This is on PostgreSQL 9.3.

Thanks,

Colin

AFAIK, extensions do not have an owner.  They just exist and are available to everyone.

If you are having a particular problem (other than owner) with an extension, it would be helpful to

post a script to illustrate that.  You should be able to drop the role without any problem.

If an error occurs, then please advise on that and include the exact message.

Hmm, I have to retract my previous statement, as the structure of pg_extension is:

CREATE TABLE pg_extension
(
  extname name NOT NULL,
  extowner oid NOT NULL,
  extnamespace oid NOT NULL,
  extrelocatable boolean NOT NULL,
  extversion text,
  extconfig oid[],
  extcondition text[]
)
WITH (
  OIDS=TRUE
);

So to solve your problem, as a superuser you can do:

SELECT oid, rolname

     FROM pg_authid

 WHERE rolname =  '{new_owner}';

SELECT oid, rolname

     FROM pg_authid

 WHERE rolname = '{user_you_want_to_drop}';

Then:

UPDATE pg_extension
   SET extowner = {oid_of_new_owner}
 WHERE extowner = {oid_from_above_statement};
