Because FillPortalStore uses dirty memory, pgss_store generates core when
handling length（query_location=1702063721, query_len=1763734642）
exceptions.
My program：
create or replace procedure p1(a inout int) as
$$
declare
a int;
begin
select 1 into a;
rollback;
select 1 into a;
commit;
end;
$$ language plpgsql;
public static void main(String args[]) {
Connection c = null;
PreparedStatement ps;
try {
Class.forName("xxx");
c = DriverManager.getConnection("jdbc:xxx://IP：PORT/postgres","user",
"user@password");
ps = c.prepareStatement("call p1(?)");
for(int i = 0; i < 10;i++){
ps.setObject(1, i);
ps.execute();
}
} catch (Exception e) {
System.err.println( e.getClass().getName()+": "+ e.getMessage() );
System.exit(0);
}
System.out.println("test end");
}
Thanks

This looks very much like the bug fixed by commit 495e73c20 [1].
I wonder whether the server is really 14.6, or something older,
because that fix shipped in 14.6.
