The following bug has been logged on the website:

Bug reference:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 19073
Logged by:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Webbo Han
Email address:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; webbohan(at)qq(dot)com
PostgreSQL version: 18.0
Operating system:&nbsp;&nbsp; all
Description:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

In function _SPI_execute_plan(), `my_tuptable` is local variable and
initialized as NULL.
If plan is canSetTag subqueries, `SPI_freetuptable(my_tuptable)` is
meaningless, because `my_tuptable` is NULL.
We'd better remove this code.
