DDC-815: Identifier quoting does not work with unique columns in PostgreSQL #5333

Jira issue originally created by user zyxist:

It seems that Doctrine ORM tries to generate invalid unique index names, when the table name is quoted and one of the columns uses the "unique" annotation:

 * Users\User
 * @Table(name="`User`")
 * @Entity
class User
     * @var string $login
     * @Column(name="login", type="string", length=40, unique=true)
    protected $login;

Expected result:

The table gets created.

Actual result:

Creating database schema...
Invalid index-name "User"*login_uniq given, has to be [a-zA-Z0-9*]
Line 33

I don't know whether the problem is caused by ORM which forgets that the table names can be quoted, or by DBAL for the same reason. Anyway, I think this should be fixed. I agree with your argumentation that identifier quoting can be wrong, but you should also remember that Doctrine can be used in cooperation with other ORM libraries or with legacy databases. I am in this particular situation: the database is shared by two different systems written in two different languages and using two different ORM libraries, and this is a big limitation for me.

  1. Why do you need SchemaTool if you have a legacy database?

  2. You can use @Table(uniqueConstraints=...) to specify the index name, this circumvents your problem

This issue has a simple workaround and no possible sane solution undoing the quoting.
