Postgres translator does not allow "text" value to be set as a Primary key

[artemklimenko-dev]

Postgres.go file has filtering which does not consider "text" value to be set as a primary key:

if c.Primary {
			switch c.ColType {
			case "string", "uuid": // make sure that we don't fall into default
			case "integer", "INT", "int":
				c.ColType = "SERIAL"
			case "bigint", "BIGINT":
				c.ColType = "BIGSERIAL"
			default:
				return "", fmt.Errorf("can not use %s as a primary key", c.ColType)
			}
		}

Agree. no need to limit to only string, uuid, and integers.

I would like to postpone this issue to the next cycle with clean up related codes.
