Multiple trees in parsetree_list
Hello All,
I am doing a project in DBMS postgresql. I have the folllowing query : in the function exec_simple_query, in which condition does the
parsetree_list include more than 1 parsetree_items? How are passed to this function from the parser/gram.c?
Thanks a lot for all the help in advance.
Best regards,
Sayali

AIUI, if there are RULEs on a table, you can get multiple queries as
the result of a single request.
