Re: PostgreSQL Limits and lack of documentation about them.

For a long time, we documented our table size, max columns, max column
width limits, etc. in https://www.postgresql.org/about/ , but that
information seems to have now been removed. The last version I can
find with the information present is back in April this year. Here's a
link to what we had:
https://web.archive.org/web/20180413232613/https://www.postgresql.org/about/

I think it's a bit strange that we don't have this information fairly
early on in the official documentation.  I only see a mention of the
1600 column limit in the create table docs. Nothing central and don't
see mention of 32 TB table size limit.

I don't have a patch, but I propose we include this information in the
docs, perhaps on a new page in the preface part of the documents.
