What does "top" show for memory usage of the processes in question?

How much memory do you have in the machine?

OK, so given your original error message:
"Dumping table TRANSACTIONS...
........................................................DBD::Pg::st
execute failed: ERROR:  out of memory
DETAIL:  Failed on request of size 16."

It looks to me like this is on your Windows box (256MB). This leads us
to two questions:
1. What is that machine showing for its memory usage?
2. What do the logs for PostgreSQL say on that machine?
