Along those lines, here's a draft patch to do just that. It handles
array type oids as well. Run it like this:
perl reformat_dat_file.pl --map-from 9000 --map-to 2000 *.dat
There is some attempt at documentation. So far it doesn't map by
default, but that could be changed if we agreed on the convention of
9000 or whatever.
