Doesn't this quoting thing seem like a usability problem? I mean,
there's no way you can possibly know what string to use unless you first
verify the contents of the file yourself. I think this is something
that should be done automatically by psql.
But, really, having to read stuff and transform into a quoted literal
seems wrong to me. I would like something that would read into a client
variable that can later be used as a positional parameter to a
parametrized query, so
\ib homer ~/photos/homer.jpg
insert into people (name, photo) values ('Homer', :homer);
and have psql turn that into
PQexecParams("insert into people (name, photo) values ('homer', $1)", some_array_with_homer);
so that no quoting needs to happen anywhere.
