Quote Oracle user password - #7043

The DBAL, when building a CREATE USER statement, uses the password as is w/o any escaping. This way, it will fail to create the user if the password contains special characters. For example:

SQL> create user bob identified by Password!;
create user bob identified by Password!
                                      *
ERROR at line 1:
ORA-00922: missing or invalid option
Help: https://docs.oracle.com/error-help/db/ora-00922/

Per the documentation,

Passwords must follow the rules described in the section "Schema Object Naming Rules" [...]

Which documents the common quoting rules:

Nonquoted identifiers can contain only alphanumeric characters [...]

Quoted identifiers can contain any characters and punctuations marks as well as spaces [...]

Which basically means that we need to quote the password:

SQL> create user bob identified by "Passw0rd!";
User created.

In my understanding, unlike other database objects, passwords are always case-sensitive, even if declared as unquoted. So it's not a breaking change. Furthermore, I very much doubt that this method is used for anything else than testing (the method creates a new user with the same password as the password of the current user).
