Hello, We are just about to wrap up our book, Pratical PostgreSQL (the one that used to be The Elephant never forgets) and we have a question. There is an obvious benefit to the use of cursors within a persistent environment. In other words, if my connection to the database is live, I can increase my query and display efficiency through the use of a cursor. However, this seems to be useless within a web based environment. If we have a live connection through a C++ application, we can perform a transaction and interact within the results. However, using something like PHP will not allow this because HTTP is stateless and PostgreSQL will not know from one transaction to the next that the results of the connection are related. Is this truly the case, or is there a way for PostgreSQL to remember the connection identifier so that the next time a PHP connection is made with the same identifier a transaction can be completed?
