The following documentation comment has been logged on the website:

Description:
The documentation for chapter 52 does not clearly identify the schema
associated with the system catalogs in either the chapter header or overview
sections; had I not stumbled across a reference in the documentation for the
postgres_fdw to the pg_catalog search path, I would have been unable to
reference the content in those catalogs via foreign data wrappers, and
although the majority of the content has been exposed via the
information_schema views and tables, there remain a few elements of interest
that appear to only exist in the pg_catalog qualified content.
