from the psql user interface, you can use the following command:

\dt
to list all table in the currently set schema

\d [table_name]
the see the table attributes

\d+ [table_name]
to see additional table attributes

Yes and no.  The psql client has a series of \ commands that can
describe pretty much anything in the db in a pretty print nature and a
minimum of typing.  The \ commands are NOT implemented in the backend,
but in the psql client so you can't just hit the db with \d from a
libpq connection to get a list of all tables / views / sequences.

However, you can use psql -E to have psql show you al lthe queries
it's throwing at the backend to get that pretty output, and then you
can take what it's doing and either wrap it in a view for future use,
or run it directly.

Not sure how desc table_name works in Oracle, but from psql you can use:
\dt table_name

Issue \? in psql for more information.
