Обсуждение: showing table and columns

Is there a way to construct a SQL statement to retrieve all the tables
and also columns information ?

I know, using \d from psql shows the table and \d tablename will show
the columns but that does not work from within jdbc.

Thanks

Sure, that's answered in the PostgreSQL FAQ:

You can read the source code for psql in file
pgsql/src/bin/psql/describe.c. It contains SQL commands that generate
the output for psql's backslash commands. You can also start psql with
the -E option so it will print out the queries it uses to execute the
commands you give.

I'm inclined to tell you to read the jdbc api specs, and you should, but
the answer is DatabaseMetaData.getTables, etc.
