public string list_keys ()
Warning: list_keys is deprecated since 2.46.
Introspects the list of keys on this.
Use list_keys instead.
You should probably not be calling this function from "normal" code (since you should already know what keys are in your schema). This function is intended for introspection reasons.
You should free the return value with strfreev when you are done with it.
