How to view the list of tables?

From

Hello, list!
I need to view the list of tables in a database. In MySQL I can do it with the command "SHOW TABLES". What about
PostgreSQL?
Can I also see somehow the datatypes of tables' fields?

\dt in psjl lists tables

( \d gives you things like sequences as well)

\d tablename shows its layout.

"man psql" will show you details of how to operate the psql application,
or when in it try "\?" and "\h" to get help. We also now support the
SQL-standard "information schema".

You'll also find the manuals have this information - available with your
installation and also online at http://www.postgresql.org/docs/

All tables:

select ...
from pg_catalog.pg_class
where c.relkind='r';


All tables of the public schema:

select ...
from pg_catalog.pg_class c join pg_catalog.pg_namespace n on c.relnamespace=n.oid
where c.relkind='r' and n.nspname='public';


KD> Can I also see somehow the datatypes of tables' fields?

select ...
from pg_catalog.pg_class c join pg_catalog.pg_attribute a on
c.oid=a.attrelid join pg_catalog.pg_type t on a.atttypid=t.oid

See also:

\d pg_class
\d pg_namespace
\d pg_attribute
\d pg_type

In psql, you can try '\dt' and '\d table name'. Type \? for more commands..
