Oh good. That's almost what I did:
I made a schema only dump, then a data only dump with --inserts. Then I commented-out the constraints from the schema. Then I loaded the data. Unfortunately, the INSERT statements take 24 hours instead of 4 hours to restore. When you say the "default" options - what format does that write? Should I have used -Fp to make a plain text backup but not --inserts? Then it would be doing a COPY instead of an INSERT and maybe that would be faster. Oh well.

I have several .SQL files created from pg_dump, and I find that when I

INSERT statements in the dump are not in the correct order. After
reading the docs, mailing lists, and googling, I see posts saying this
problem was fixed back in the 7.x days.
It is not fixed and is sometimes not possible to fix for data only dumps.
Since I did a data only dump, I think my only option is to create the
schema, manually disable all the constraints, then restore, then
re-enable the constraints.
Much easier:
1. Create a schema with all constraints etc.
2. Dump this empty database with pg_dump with default options to
empty_database.sql.
3. Split empty_database.sql file to 2 files - tables.sql and
constraints.sql - all constraints will be at the end of empty_database.sql
4. drop database, create empty one, import tables.sql, import your
data-only backup, import constraints.sql.
