http://www.postgresql.org/docs/current/static/features.html doesn't
contain "fold" (as in "case folding") at all, doesn't this topic
belong rather there? The FAQ entry could point to, and maybe extend,
the (still nonexistent) text in that document.

Something like this is missing from
http://www.postgresql.org/docs/current/static/overview.html.

This is missing from
http://www.postgresql.org/docs/current/static/sql-createindex.html
and/or http://www.postgresql.org/docs/current/static/indexes.html
