One could say your current error is just a variation of the above.

That would be a useful data point, though given the above if it succeeds
it mainly proves Tom's point, that using BINARY in your situation is a
hit and miss exercise.

Have you tried doing something like?:

pg_dump -d production -U postgres -t projection -a > proj_txt.sql

pg_dump -d production -U postgres -t projection -a -Z 5 > proj_txt.sql.gz

l -h proj_txt.sql*
-rw-r--r-- 1 aklaver users 3.2M Jul 4 09:23 proj_txt.sql
-rw-r--r-- 1 aklaver users 560K Jul 4 09:23 proj_txt.sql.gz
