I ran a DOS batch file. Here's the first few lines:
"\program files\postgresql\8.1\bin\pg_dump" -f schema.sql -v -s -h
159.138.80.150 -U postgres -X disable-triggers Anneal > backup_in_pieces.log
"\program files\postgresql\8.1\bin\pg_dump" -f adhoc_query.sql -v -a -t
adhoc_query -h 159.138.80.150 -U postgres -X disable-triggers Anneal
"\program files\postgresql\8.1\bin\pg_dump" -f base_cycle_compatibility.sql -v
-a -t base_cycle_compatibility -h 159.138.80.150 -U postgres -X
disable-triggers Anneal
"\program files\postgresql\8.1\bin\pg_dump" -f base_type.sql -v -a -t base_type
-h 159.138.80.150 -U postgres -X disable-triggers Anneal
Thanks again for your help!

What method did you use for that process?
