Oracle SQL 'comment on ...'

I just discovered Oracle SQL's handling of inline documentation. Is
there an equivalent feature in PostgreSQL?

Here are the oracle notation:

comment on table student_status_info is
'Information on the students current status at RPI. In part used to put some aspects of check-in online. This is data taken from the SRS.K0 table. Other K0 fields go into simon.students.';

comment on column student_status_info.person_id is
'The simon people.id of this person. Used to join with other tables.';
