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

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.
