Use the term "system catalog" rather than "system relation" in assorted places where it's clearly referring to a table rather than, say, an index. Use more natural word order in the header boilerplate, improve some of the one-liner catalog descriptions, and fix assorted random deviations from the normal boilerplate. All purely neatnik-ism, but why not. John Naylor, some additional cleanup by me Discussion: https://postgr.es/m/CAJVSVGUeJmFB3h-NJ18P32NPa+kzC165nm7GSoGHfPaN80Wxcw@mail.gmail.com
