Check as to wheteher the names of tables are in the plural or in the singular form. Make sure that you are consistent in naming. Show the number of tables that name is in plural or in singular by table type.
Notes
The query works somewhat correctly only if the names are in English. The query is based on a simplified assumption that in case of many words in English (of course, not all) the plural form is indicated by the letter "s" at the end of the word. If the name or its subcomponent ends with s and it is not preceded with an undersore and a single letter or a letter "s", then it is considered plural. Thus, "process" and "task_fs" are considered singular whereas "processes" and "clear_facts" are considered plural.
