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_opclassWHERE 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 !
