* This method decides whether or not a specific object should be able
* to use external databases.
*
* Arguments:
* ob is the object performing the db_* query
* action can be one of the following strings:
* connect, close, exec, commit, fetch, rollback
* these correspond to the db_* functions
* info is any extra information depending on the action
* For 'connect' it is an array of the form: ({ database, host, user })
* For 'exec' it is an array of the form: ({ exec string })
* For other types of action it is an empty array.
*
* Return value:
* For actions other than 'connect', a return value of 0 disallows the
* action and generates an error, while a return value of 1 allows the
* action.
* For 'connect', the return value can be a password for the
* database, or 1 if the database has no password or 0 to prevent
* connection.
*
* @param ob the object performing the db_* query
* @param action "close", "commit", "connect", "exec", "fetch" or "rollback"
* @param info additional data depending on the action
* @return 1 to allow, 0 to deny, for action "connect" return the
* password to send to the database as a string (or return 1 if no
* password is needed)
