* Dump/restore comments only?

Folks,
There have been a number of times when I've wanted to ignore everything
in a dump file apart from comments. I am interested not just in comments
for tables/views/columns but constraints, indices and functions as well.
Many of my comments are multi-line and often resemble manpages, so a
simple grep for '^COMMENT ON' will not work for me.
Has anyone got a script/view in SQL that will generate fully-qualified
COMMENT ON statements from the pg_catalog/information_schema, a
sed|awk|perl script to munge the ascii file produced by pg_dump,
or even pg_dump undocumented options that might help me?
(If there are no such options for dump/restore, might these be useful
inclusions in the future?)
Thanks in advance.

You might find it simpler to do this if you use the
custom format. Something like :
pg_dump -Fc mydat > mydat.dump
pg_restore -l mydat.dump > mydat.toc
grep COMMENT mydat.toc > mydat.comments.toc
pgrestore -L mydat.comments.toc mydat.dump
