In Oracle, ALTER TABLE MOVE in 8i was a godsend, finally enabling a table reorganization without export/import.
My timid management forbade an upgrade from Oracle 7.3.4 until 2013. It was agony to remain on that museum piece for as long as we did.
I am upgrade-minded, but my management is not. I always lose.
I am retiring in two years. I will not miss their problems, not at all.
Edit: Oracle 10g was the last release that (for us) brought must-have features. Sure, upgrading to 19 or 23 would be great, but it doesn't bring anything that I really want.
