In that case I humbly submit that there is a case for reviving the
psql patch I posted that kicked off this whole thing and lets you
export a piece of binary data from psql quite easily. It should
certainly not involve any protocol break.
The psql only solution can work only for output. Doesn't help with input.
The I would suggest we try to invent something for psql which does help
with it. I just don't see this as an SQL problem. Pretty much any driver
library will have no difficulty in handling binary input and output.
It's only psql that has an issue, ISTM, and therefore I believe that's
where the fix should go. What else is going to use this? As an SQL
change this seems like a solution in search of a problem. If someone can
make a good case that this is going to be of general use I'll happily go
along, but I haven't seen one so far.
