Instead of polling from a custom program, what would be nice is a feature within shell.c that permits the user to specify pre-execute SQL which optionally executes silently before every statement sent through the input line. Testing SCHEMA_VERSION for changes as you suggest (and many other useful refresh type operations) could then be implemented without need of custom application development.
Such a feature would simplify CPU efficient integration of a more lively and au courant command line as other processes change the database. A post-execute SQL feature in shell.c would also have many live integration uses.
