[HACKERS] a question about exec_simple_query()

2008-06-09 Thread 汪琦 
Hi, everyone:

In functin exec_simple_query(), why we run a simple query 
wrapped in a portal.

For instance:

version 8.3.0 ,postgres.c, Line 908

/*
 * Create unnamed portal to run the query or queries in. If 
there
 * already is one, silently drop it.
 */
portal = CreatePortal("", true, true);

..


In other words, what's the benifit we use a portal to run a 
simple query?


Thanks for your help!  :)
