[RFC]: SQL Metadata Backed Enums

[simon-mundy]

Proposed Version

0.4.0 - 1.0.0

Basic Information

During refactoring, it has been noted that some class constants should/could be turned into Enums to help in more tightly constraining and documenting the classes.

An example is PhpDb\Sql\Metadata\Object\ConstraintObject.php with the following:

/**
 * One of "PRIMARY KEY", "UNIQUE", "FOREIGN KEY", or "CHECK"
 */
    protected ?string $type = null;

This issue proposes to create a MetaData\Object<xxx>Enum for the various lists that are required.

Well, the real benefit is they become actual types.
