Обсуждение: pg_get_keywords descriptions

=> select distinct catcode, catdesc from pg_get_keywords(); catcode |        catdesc

Unreserved

I find the descriptions of C and T quite confusing.  For example, saying 
that "authorization" is a "type or function name" (T) is somewhat bogus.

In 
http://developer.postgresql.org/pgdocs/postgres/sql-keywords-appendix.html, 
the terms

C = non-reserved (cannot be function or type)
T = reserved (can be function or type)

are used.  Should we use these here as well (possibly adding "name")?
