Callers should always zero out the entire <parameter>options</parameter>
struct, then fill whichever fields they want to set. This ensures forward
compatibility of code, since any fields that are added to the struct in
future will be defined to behave backwards-compatibly if they are zero.
The currently available <parameter>options</parameter> fields are:

<para>
<literal>DestReceiver</literal> object that will receive any tuples

The resource owner that will hold a reference count on the plan while
it is executed. If NULL, CurrentResourceOwner is used. Ignored for
non-saved plans, as SPI does not acquire reference counts on those.

<para>
When <parameter>options->dest</parameter> is NULL,
<varname>SPI_processed</varname> and
<varname>SPI_tuptable</varname> are set as in
<function>SPI_execute_plan</function>.
When <parameter>options->dest</parameter> is not NULL,
<varname>SPI_processed</varname> is set to zero and
<varname>SPI_tuptable</varname> is set to NULL. If a tuple count
is required, the caller's <literal>DestReceiver</literal> object must
calculate it.
