hello,
I have read the source code of postgres.c. Two strang things I can't understand.
Souce code of Postgres.c:
..
Foreach(parsetree_list的元素parsetree){ //In what situation here will be many parsetrees？
…
(List *)querytree_list = pg_analyze_and_rewrite(parsetree);foreach(querytree_list中的每个querytree){ //In what situation
herewill be many querytrees？
Who can tell me the reason?
Thank you very much
