Add information about access method for partitioned relations in \dP+

Browse Source 
Since 374c7a229042, it is possible to set a table AM on a partitioned
table.  This information was showing up already in psql with \d+, while
\dP+ provided no information.

This commit extends \dP+ to show the access method used by a partitioned
table or index, if set.
