Right. It isn't something I recommend running in production before every insert. It's just something I have done sometimes, like as part of a big database change, and only to "reference" tables. Like suppose there is a table of 10 rows to populate a dropdown menu. Now I need to add an 11th, but for some reason the sequence got out of wack, and the next sequence value is 15. So I manually set it back to 11.
