thank you very much for pointing me to dynahash, here is the
next version that finally seems to work.

Two patches are attached, the first is the absolute minimum for
making it work, this still has the Tree type for canon_pathkeys
and eq_classes got the same treatment as join_rel_list/join_rel_hash
has in the current sources: if the list grows larger than 32, a hash table
is created. It seems to be be enough for doing in for
only, the other users of eq_classes aren't bothered by this change.

That's better, but can't you use dynahash for canon_pathkeys as well?
