You can try creating index/triggers first and load the data. At the end it will
take a while before you get a usable database with either approach but see what
works faster for you.

Personally I was in a situation where postgresql was hogging space while
creating index on a table that had 81M rows with 3GB disk footprint. I dropped
the table and recreated it. Also created index before loading data. The loading
was slow with this approach but it finished in 3 hours. And I had an updated
index as well. Just had to run vacuum over it.

Take your pick..
