title: Find all multipolygons from one table within another
body: <p>So, I've got two tables - PLUTO (pieces of land), and NYZMA (rezoning boundaries). They look like:</p>
  
  <pre><code>    pluto                   nyzma
  id | geom                name | geom
  --------------------     -------------------
   1 | MULTIPOLYGON(x)       A  | MULTIPOLYGON(a)
   2 | MULTIPOLYGON(y)       B  | MULTIPOLYGON(b)
  </code></pre>
  
  <p>And I want it to spit out something like this, assuming that PLUTO record 1 is in multipolygons A and B, and PLUTO record 2 is in neither:</p>
  
  <pre><code>pluto_id | nyzma_id
  -------------------
      1    | [A, B]
      2    | 
  </code></pre>
  
  <p>How do I, for every PLUTO record's corresponding geometry, cycle through each NYZMA record, and print the names of any whose geometry matches?</p>
