If the output file is in custom format, that last step shouldn't work
since custom format isn't parsable by psql. That would only work if
it was dumped in plain format.

Your original dump specifies a compression level, but you didn't
specify "-F c" for custom format, which would use the compression
level.

Is your file human readable? Try running "file Trading-Access" on the
file. What does it say?
