PRIMARY KEY parameters

Hi,

Page https://www.postgresql.org/docs/9.1/sql-createtable.html states:

[quote]

[ CONSTRAINT constraint_name ]
{ NOT NULL |
NULL |
CHECK ( expression ) |
DEFAULT default_expr |
UNIQUE index_parameters |
PRIMARY KEY index_parameters |
REFERENCES reftable [ ( refcolumn ) ] [ MATCH FULL | MATCH PARTIAL |
MATCH SIMPLE ]
[ ON DELETE action ] [ ON UPDATE action ] }
[ DEFERRABLE | NOT DEFERRABLE ] [ INITIALLY DEFERRED | INITIALLY IMMEDIATE ]
[/quote]

And then:

[quote]

index_parameters in UNIQUE, PRIMARY KEY, and EXCLUDE constraints are:

[ WITH ( storage_parameter [= value] [, ... ] ) ]
[ USING INDEX TABLESPACE tablespace ]
[/quote]

How can I retrieve those 2 parameters?

Thank you
