ALTER TYPE ... ADD VALUE issue

[Victor Yegorov <vyegorov@xxxxxxxxx>]

Greetings.

I'm observing the following on 9.3.5 and also on 9.4beta3:

\set AUTOCOMMIT on

CREATE TYPE enum_type AS ENUM ('bad', 'good');

CREATE TYPE

ALTER TYPE enum_type ADD VALUE 'so-so' AFTER 'bad';

ALTER TYPE

DROP TYPE enum_type;

DROP TYPE;

\set AUTOCOMMIT off

CREATE TYPE enum_type AS ENUM ('bad', 'good');

CREATE TYPE

COMMIT;

COMMIT

ALTER TYPE enum_type ADD VALUE 'so-so' AFTER 'bad';

ERROR:  ALTER TYPE ... ADD cannot run inside a transaction block

What is wrong here?
