How could I dump using the custom format, and then use "dumpfile" with 
pg_restore to restore the dump? If I just prepend the comment to the 
file, then pg_restore will choke, since the file won't be in the proper 
custom format. I would have to remove the comment before sending the 
file to pg_restore. Is there an easy way to do that? That can be easily 
automated, and not take a huge amount of time given a 4 gig dump file 
that must be modified?

Given those requirements, building a commenting mechanism into the 
custom format would work out very nicely, I think.

Thanks!
