how to get info about tables in remote dB?

Hi,

I am using PostgreSQL JDBC driver to connect to PostgreSQL server. And I need to get a list of tables under the current user and get information about tables - # of tables, # of columns in them, type of columns, etc.

    For intanse, in oracle I could this by running:

        select * from user_tables; -- give the list of tables

        descr table_name; - gives information about the table

 

Ideas?

Thanks,

Mykola
