The only occurrences of that string that I can find in the source code
are in plpgsql: the various forms of EXECUTE throw that error if the
expression that's supposed to yield a query string yields NULL instead.
However, if that's what was happening then you should have seen some
indicator that the error was in a plpgsql function, not just the bare
error message.
