[DOCS] Functions-info.html

The following documentation comment has been logged on the website:

Page: https://www.postgresql.org/docs/9.1/static/functions-info.html
Description:

From https://www.postgresql.org/docs/9.1/static/functions-info.html, table
9-49 and elaboration on:

has_database_privilege

It is not clear to me by reading the documentation whether access granted
through public or a role is considered also for determining the return
value.

Would help me when that would be stated explicitly.
