If this is "\a\t except we aren't removing column headers", then it
seems like "\graw" is a remarkably misleading name for the functionality.
I'd been assuming, from reading no more than the patch subject line,
was that it was something like "dump the raw field data with no headers,
footers, or separators", with a claimed use-case involving passing bytea
data to some consumer or other.
FWIW, I concur with Robert's assessment, both that the use-case is pretty
thin and that we do not want to get into the business of encouraging a
boatload of \gxxx variants, especially not ones with randomly chosen names.

That seems like an argument for new pset option(s) to suppress footers
but not headers. It's not an argument for invoking such options through
a \g variant; that's totally non-orthogonal.
