I try with options : -n public (without -b) but it's always the same, the dump is huge.
According to the man page that should have done it: Note: Non-schema objects such as blobs are not dumped when -n isspecified. You can add blobs back to the dump with the --blobs switch.
I guess the next question is 'what does postgresql considers a blob'? bytea fields? How about a large text with megabytes worth of data?
