Agreed. But adding language features, especially syntactical ones,
demands prudence; there is good reason to limit keywords like that.
What about:
pgsql.rows
pgsql.found
pgsql.sqlerrm
etc
as automatic variables (I think this was suggested upthread).
Conflicts with existing structures is of course an issue but I bet it
could be worked out.
I also kinda disagree on the brevity point, or at least would like to
add some color. SQL is verbose in the sense of "let's make everything
an english language sentence" but incredibly terse relative to other
language implementations of the same task. Embedded SQL tends to be
uniformly clumsy due to all of the extra handling of errrors,
parameterization, etc. This is why we write plpgsql naturally.
