Fix thinko in SPI_execute_plan() calls
Fix thinko in SPI_execute_plan() calls

Two call sites were apparently thinking that the last argument of
SPI_execute_plan() is the number of query parameters, but it is actually
the row limit.  Change the calls to 0, since we don't care about the
limit there.  The previous code didn't break anything, but it was still
wrong.
