Comment (by robe):

 based on discussion on irc with Darafei

 I did this:


 {{{
  update pg_operator set oprcanhash = false, oprcanmerge = true where
 oprname = '=' and oprcode = 'geometry_eq'::regproc;

 }}}


 and then the test on bessie32


 {{{
  with mj as (select 'POINT(0 0)'::geometry geom) select '#4394' from mj a
 full join mj b on a.geom = b.geom;
 }}}

 Yielded 1 row as it should.

 Both in 3.0 are set to true.

 So it seems there is something wrong with our hashing logic on 32-bit.
