Dept of second thoughts: actually, perhaps see if you can generate the
pg_description entries from the C comments in the include/catalog header
files. There's already a strong motivation to hold those to
shorter-than-a-line length, whereas the column descriptions in
catalogs.sgml tend to run on a little longer, and wouldn't format nicely
in \dt+.
