Last time I had to do this kind of exercise, a few years ago, I was in a
remote place without Internet access, so I could not get any information
or ask any help. I was kind of surprised/frustrated by the (apparent)
lack of order of the pg_dump output. So I manually wrote scripts to
export the tables and views' definitions separately, one by one, (using
pg_dump, of course) and stack them in the order I wished into a large
file. That was quite suboptimal, but it worked as expected, and I was
able to diff and patch correctly.
You realize there is pg_restore -l and pg_restore -L :

Yes, thanks for the advice. Now I remember that I had used it also: I
just found these notes in my numeric attic:
# pierre@autan: ~ < 2013_08_17__17_00_23 >
pg_restore -l database_2013_08_14_20h34.pg_dump -n pierre > tt_schema_pierre
# pierre@autan: ~ < 2013_08_17__17_00_23 >
vi tt_schema_pierre
# pierre@autan: ~ < 2013_08_17__17_00_23 >
cat tt_schema_pierre
DROP VIEW IF EXISTS pierre.dh_collars;
DROP VIEW IF EXISTS pierre.dh_litho;
DROP VIEW IF EXISTS pierre.dh_sampling_grades;
DROP VIEW IF EXISTS pierre.dh_sampling;
DROP VIEW IF EXISTS pierre.topo_points;
DROP VIEW IF EXISTS pierre.baselines;
DROP VIEW IF EXISTS pierre.dh_devia;
...
I just cannot remember why it did not fulfill my needs, so that I rather
opted to pg_dump's.
...
It does not solve all problems but it does do some ordering and is amenable to be
imported as space separated file for further ordering :
aklaver@panda:~> pg_restore -l test.out

Thanks, I'll dig a bit more in pg_restore, for my current issues.
