From my perspective, the easiest and fastest way to do this is to create the
table definitions in PostgreSQL, and then to use Perl to convert the data
format to something COPY will recognize. If you can do the create table
statements for the LM* data, I can do the Perl scripts.
Given that the *total* data is 20G, we'll want to use a subset of it. Per
your suggestion, I am downloading the *LM* tables. I may truncate them
further if the resulting database is too large. If some of the other tables
are reference lists or child tables, please tell me and I will download them
as well.
