describe command

Postgresql:

Oracle has a command "describe"

e.g.

"describe cars" or  "desc cars"

where cars is the name of the table.

this command  describes the attributes of a table.

e.g.

Name        Null        Type                Constraint
------------------------------
VIN                           char(20)        Primary key
Make        Not Null   varchar(20)
Model                        varchar(20)

Does Postgresql have anything similar?
I could find the command "describe" anywhere in the documentation.
