Hello,

We currently use prepared statements for most of the work an app does, as an SQL injection protection and for other reasons.

There's one statement which can't be prepared:

SET LOCAL myprefix.mysetting = 'my setting value';

Ideally, I'd like to be able to do

PREPARE test(text) as SET LOCAL myprefix.mysetting = $1;

but this isn't supported (currently on PG 9.3)

I suspect the answer is 'no' but no harm in asking if it's likely to be considered in future. I can't see it here: https://wiki.postgresql.org/wiki/Todo

​Given that you can simply use the "set_config(...)" function I'd say that this command will have not particular in the decision work on improving this limitation in the system.
