To date any commands run under database have completed
successfully, however it appears that the package does
not automatically load when octave starts.
If I then run
octave > pkg load database
this does bring the package online, and it appears there
is an option within the package to load automatically.
Is this the expected behaviour?
I have appended an example of use of the package as this
may be useful to others attempting to use the database
package
