"character 24" is not anywhere near where the $1 symbol is in that
query string, so I'm betting that this error does not refer to the
outer client-submitted query but to some plpgsql or sql function that
is getting invoked along the way.  Since you've provided exactly no
context for this log snippet, it's hard to speculate further than
that.

(And yeah, if that is how such a problem gets logged then I agree
we could stand to work on providing better error context.  But again,
without a reproducible test case it's hard to make any progress.)
