Valid DB Identifiers

We’ve chosen to limit valid database identifiers in cases where we accept user-supplied names. Any time you provide a database identifier name, like when renaming a table or create a sync target, the identiier must conform to these rules:

• Begin with an upper or lowercase ASCII letter (a-zA-z).
• Contain only upper or lowercase ASCII letters, numbers, underscores, and spaces (a-zA-Z0-9_ ).

That it, it must match the regular expression /^[a-zA-Z][a-zA-Z\d_ ]*$/.
