​The only way a table becomes "full" is if you run out of disk space - and
you should be monitoring that at the O/S level and not at a database table
level...

​As for clients - if they are inserting data they will simply get failures
when they attempt to do so - for me that seems like sufficient notification
for something that should rarely if ever happen.
