I tend to revise my posts… A lot.
This is particularly true for my essays. I will stew on the text for several days, often saving very minor revisions. As a result there may be 20-30 revisions in the database. I also tend to find a few errors during proofreading that require another save or three. All this editing does add a bit of a clutter.
I do like the WordPress revision feature, it has saved the day more than once. The ability to recover the text from previous versions is simply invaluable.
WordPress does have some tools for dealing with the revisions. Even if you have to know about some of the behind-the-scenes stuff to make changes to revision handling.
Finding how to do this is done through the usual learning materials… A Google search for something like “WordPress limit revisions” provides all you need to know. The information was out there, but I will repeat it here. If nothing more this post can serve as notes for when I next need to purge the database.
