To retrieve the table names , use the pg_tables :
SELECT tablename FROM pg_tables WHERE tablename NOT LIKE 'pg_%';

To retrieve the column names , you can use the pg_attribute and
pg_type tables :
SELECT attname , typname FROM pg_attribute , pg_type WHERE
typrelid=attrelid AND typname = 'banals' ;
if your table name is 'banals' , but this will give you 6 columns that
you haven't declared : cmax,xmax,cmin,xmin,oid,ctid .

If you want column names with its type :
SELECT attname , opcname , atttypmod FROM pg_attribute,pg_type,
pg_opclass WHERE attrelid=typrelid AND atttypid=opcdeftype AND
typname = 'banals' ;
if your table name is 'banals' , but this will give the
column 'oid' you haven't declared

You can find all tables names in <where you put psql>//data/base/ .

Sorry for my english !
