Big +1 on that..  I *still* do it by hand much of the time these days
(manually hacking out the CREATE TABLE step from the ALTER TABLE; CREATE
INDEX piece).  We took some steps towards improving that using custom
dump formats, iirc, but the patch Simon (iirc) for adding options to
pg_dump to have it split things out for the SQL-style dump never did get
in (think there were dependency issues and whatnot, and I have to admit
that it didn't really have the best UI/parameters).

Perhaps we should have a 'multi-file' option with a 'base-file-name'
parameter which then generates:

pre-data DDL
data
post-data DDL
psql script to run them in order (\i-style)

?

Just my 2c.

    Thanks,
