Should we call it quits on support for 32-bit

[Regina Obe]

I feel a little uneasy about declaring 32-bit systems dead, but
apt.postgresql.org (and I assume Debian upstream), is about to declare no
longer supporting 32-bit systems.

How do people feel about this.  On the one hand I feel like some of those
32-bit failures deserve further investigation.

Poor berrie has been crashing on garden tests ST_MakePolygon(Nan ...) for a
while, I'm sure it's fixable, and it's our fault and we should do something
about it, but berrie64 is doing fine on the same tests.

And this - https://trac.osgeo.org/postgis/ticket/5461  

And I can't remember the last time I saw 32-bit gitlab happy -
https://gitlab.com/postgis/postgis/-/jobs/7550985291

Part of me worries, are these true errors we are only seeing because of the
smaller bit space or have we just gone beyond 32-bit that we just shouldn't
care.

Anyone have thoughts on the matter?

Thanks,
Regina
