PostgreSQL (latest versions at least) has an optimisation if you create a
table in the same transaction as you load data into it. So, if you have a
database dump, load it in using psql -1, which wraps the entire operation
in a single transaction. Of course, a COPY dump will load a lot faster
than a INSERT dump.
