unquoted EXPORT for enum with same name as keyword

[c-meier]

What happens?

When exporting an enum with the same name as a keyword, the enum name is not quoted.

To Reproduce

CREATE TYPE "group" AS ENUM ( 'one', 'two');
CREATE TABLE table1(col1 "group");
EXPORT DATABASE 'test_export' 

Which generates a test_export/schema.sql that can't be imported:

CREATE TYPE group AS ENUM ( 'one', 'two');
CREATE TABLE table1(col1 group);
