Please post a real example instead of a "model." The code you
posted fails to compile, with errors and warnings like the following:
spitest.c: In function `myspi':
spitest.c:18: `ret' undeclared (first use in this function)
spitest.c:18: (Each undeclared identifier is reported only once
spitest.c:18: for each function it appears in.)
spitest.c:39: warning: passing arg 2 of `SPI_execp' from incompatible pointer type
spitest.c:41: warning: implicit declaration of function `SPI_finnish'
spitest.c:16: warning: unused variable `res'
Since what you posted doesn't compile, it can't be what you're
really doing; that means we have to guess at what the real code
looks like. It would be easier to help if we could see the real
thing so we don't have to guess.

val is a bytea * but the second argument to SPI_execp() is a Datum *
(the compiler warning hints that something's wrong here). Try
something like this:
Datum values[1];
values[0] = PointerGetDatum(val);
ret = SPI_execp(plan, values, NULL, 1);
That works for me in simple tests. If anybody sees a problem with
it then please make corrections.
