title: $libdir/odbc_fdw is missilng
body: <p>I am using cartoDB and Postgres 9.3 including PostGIS. When I try to create development user in cartoDB I get this error:</p>
  
  <p><code>PG::Error: ERROR:  could not access file "$libdir/odbc_fdw": No such file or directory: CREATE EXTENSION IF NOT EXISTS odbc_fdw SCHEMA publi</code>c</p>
  
  <p>Also, when I try to run odbc_fdw extension inside Postgres I get the same error.</p>
  
  <p>Any idea how to fix it?</p>
