Re: psql metaqueries with \gexec

I'm getting a warning from this patch:

1 warning generated.

(note that I'm using CC='ccache clang -Qunused-arguments -fcolor-diagnostics')

        for (r = 0; r < nrows; r++)
        {
                for (c = 0; c < ncolumns; c++)
                {

etc...

Normally we don't use gratuitous {'s, and I don't think it's helping anything in this case. But I'll let whoever commits this decide.

FWIW, it's generally better to leave that kind of re-wrapping to the next pg_indent run.

I added tests for ON_ERROR_STOP. New patch attached.

The patch still needs to document this feature in the psql docs (and maybe the manpage? not sure how that's generated...)
