Database Naming Rules

The keyword length of RDS for PostgreSQL is limited to 63 bytes. Therefore, it is recommended that the length of a database name be no more than 30 characters.
A database name can contain only lowercase letters, underscores (_), and digits. Do not use reserved keywords in database names or begin a database name with pg, digits, or underscores (_). For details about reserved keywords, see the official documentation.
