That will dump all schemas from that db. If you only want a particular

There is no '-t' at least in 8.1.1..
'-T' on the other hand lets you specify an existing db and it will use
that as a base instead of template1.

second one and that will copy everything across but that includes your data.

You can dump particular tables only but you don't get anything more
selective.
