[FEATURE] Add support for more data type

Is your feature request related to a problem? Please describe. A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]

• Enums: In PostgreSQL, enumerated types are available as a data type. I use enums in my data model design, and I would love to have this feature added, as it simplifies development.
• Custom Data Types: PostgreSQL plugins enable access to additional data types. Instead of adding each possible data type in DrawDB, I suggest implementing support for custom data types. This would allow platform users to utilize extra data types provided by plugins, such as ULID and enums.

Describe the solution you'd like A clear and concise description of what you want to happen. There are two possible solutions:

1. Users can request the addition of individual data types through a feature request, which can then be integrated into the DrawDB platform.
2. Alternatively, DrawDB users could add custom data types directly in the "Data Type" section of the column user interface (UI).

Additional context Add any other context or screenshots about the feature request here.

+1 Users should be able to add custom data types directly.

We don't use any of the traditional SQL databases, thus we don't have the same field types. But would still like to design our database in drawDB then export as JSON.
