    @@ -90,6 +83,6 @@ The following system-level schemas exist in every database:
     
     -   `pg_catalog` contains the system catalog tables, built-in data types, functions,
and operators. It is always part of the schema search path, even if it is not explicitly named
in the search path.
     -   `information_schema` consists of a standardized set of views that contain information
about the objects in the database. These views get system information from the system catalog
tables in a standardized way.

is used internally by the HAWQ system.
    +-   `pg_toast` stores large objects such as records that exceed the page size. HAWQ uses
the EXTENDED strategy for column storage. It allows both compression and out-of-line storage.
Compression will be attempted first, then out-of-line storage if the row is still too big.This
schema is used internally by the HAWQ system.

    Missing a period at the end of the new sentence.  Also, is it confirmed that HAWQ uses
the EXTENDED strategy? Last comment from Stanley was that this was a guess.
