       SPI_cursor_open_with_paramlist - set up a cursor using parameters


       Portal SPI_cursor_open_with_paramlist(const char *name,
                                             SPIPlanPtr plan,
                                             ParamListInfo params,
                                             bool read_only)


       SPI_cursor_open_with_paramlist sets up a cursor (internally, a portal) that will execute a
       statement prepared by SPI_prepare. This function is equivalent to SPI_cursor_open except
       that information about the parameter values to be passed to the query is presented
       differently. The ParamListInfo representation can be convenient for passing down values
       that are already available in that format. It also supports use of dynamic parameter sets
       via hook functions specified in ParamListInfo.

       The passed-in parameter data will be copied into the cursor's portal, so it can be freed
       while the cursor still exists.


       const char * name
           name for portal, or NULL to let the system select a name

       SPIPlanPtr plan
           prepared statement (returned by SPI_prepare)

       ParamListInfo params
           data structure containing parameter types and values; NULL if none

       bool read_only
           true for read-only execution


       Pointer to portal containing the cursor. Note there is no error return convention; any
       error will be reported via elog.
