Have you been in contact with Carlos Hurtado at Universidad de Chile?
He wanted to work on a similar project.

Did you check whatever exists at techdocs.postgresql.org? Also see if
you can find related projects at gborg.postgresql.org.
For ETL the usual recomendation is to convert your data to a reasonable
ASCII representation (comma separated values, etc) and then massage it
with whatever combination of awk/sed/perl suits you. After that, feed
it to COPY or psql's \copy. There's also PgAdmin2 Migration Wizard, or
something like that.
