By default, the search path for a PostgreSQL user is set to the "public" schema. Even if you create a new schema (say, "import") any tables you create in it will not show up in a dt
listing of tables without also specifying the schema (e,g,, \dt import.*
).
Fix is to update the user's path to include the new schema:
postgres=# alter role myuser set search_path = '$user',public,import;
