OK, updated patch, with output of text bind parameters. New output is:

LOG: prepare sel1: SELECT $1 + $2;
LOG: bind sel1: SELECT $1 + $2;
LOG: bind sel1: parameter 1: "8"
LOG: bind sel1: parameter 2: "5"
LOG: execute sel1: SELECT $1 + $2;

I put each bind parameter on a separate line. Is that OK?

I also updated the documentation. Test program also attached.
