error with pg_stat_user_tables table

[datvq]

I can't generate with this query

SELECT 
  schemaname AS schema_name,
  relname AS table_name,
  n_live_tup AS total_count
FROM pg_catalog.pg_stat_user_tables 
ORDER BY relname ASC;

And get errror like this

relation "pg_stat_user_tables" does not exist

How can I fix it.

Thanks for reading.
