You could use this to generate the SQL:
\set my_table my_real_table_name
SELECT 'SELECT COUNT(*) AS total_rows, '||array_to_string(array(SELECT
'COUNT('||column_name::text ||') AS ' || column_name::text FROM
information_schema.columns WHERE table_name=:'my_table'),E',\n') || ' FROM
' || :'my_table' || ';';
