Help with PostgreSQL 9.4 to expand jsonb int array into table with row numbers

[Neil Tiffin <neilt@xxxxxxxxxxxxxx>]

Trying to wrap my head around postgresql 9.4 jsonb and would like some help figuring out how to do the following.

Given the following example jsonb:

    ‘{“name1” : value1, “name2”	: value2, “name3” : [int1, int2, int3] }’::jsonb AS table1.column1
	
Wanted: Return the “name3” array only, as a table with a return signature of 

    TABLE( var_name varchar, var_value int, var_row_num int)

So the resulting data would look like this:
	
    (‘name3’, int1, 1)
    (‘name3’, int2, 2)
    (‘name3’, int3, 3)

Assume the array could be any length except zero and ‘name3’ is guaranteed to exist.
