me too. I very much like the current behavior, so that a transaction is
aborted when lock table space is exhausted. This is pretty flexible
because you can always manipulate the lock table size. However,
Alvaro's stuff would still be nice when doing massive database changes
that are not performance sensitive.

By the way Alvaro, are you still planning to reorganize the lock union?

Hmm. I'll keep that in consideration (if we come to implement lock
table spilling.)
