chapter VI has roman numeral subsections, but V and VII both have decimal sections. thats not very consistent...
Not consistant, no. It does feel like a different *level* of documentation somehow. It seems plausible to treat this section separately, but i am not an insider on it.
If no-one answers anything useful here, you might want to try the documentation list.. pgsql-docs@postgresql.org
