Some of the many error messages introduced in458857ccmissed 'FROM unpackaged'. Alsoe016b724and45ffeb7eforgot to quote extension version numbers. Backpatch to 9.1, just like458857ccwhich introduced the messages. Do so because the error messages thrown when the wrong command is copy & pasted aren't easy to understand.
