I see. So you propose passing an array as a single param to
PQexecParams, in PostgreSQL's syntax for arrays, e.g.. "{42, 45, 50}".
Makes sense. Problem is, that, again, the application would be
responsible of making sure the individual values don't contain nasty
stuff (for example, if they are strings) before consolidating them to
one PostgreSQL array literal.
I was hoping to get away "on the cheap" on this, letting PostgreSQL take
care of the injection avoidance ;-)
I'm converging in building the query dynamically, but still with
placeholders. I /know/ how many values are coming, and how many
placeholders used so-far in the query, so it'd be fairly easy to just
insert "$m"..."$n" as needed.
Thanks a lot, Dmitri
Cheers
