The only thing the SQL standard defines to gain access to information about
tables, schemas and catalogs (=databases) is the information_schema views.
There is no "show database" or "show tables" statement in the SQL standard.
Btw: \dt is a command specific to the psql client - it's not a general
"SQL command" in Postgres
