That is a tricky question.

here, we deploy a major update to the system every 6 weeks. All database changes go into the major update.

We release patches to production frequently. In first week of the major update we might do 5 - 6 patches per day.

This is not easy for us, as we do not have everything on the web.

We have a java application that is patched and downloaded from our users so we want to avoid forcing them to download the new stuff too often.

if it was a web application the impact of the patch would be minimal.
