First you can create a file with the SQL statement:
select tablename from pg_tables where schemaname not in
('information_schema','pg_catalog' ) order by tablename;
After, run it by psql:
psql -U [postgres_user] -d [database_name] -f [file_created_with_SQL]
> [output_file]
This will dump all non-database schema tables into the output file, so
you can open it and read table names.
