I am building an app using php and postgresql. My questionis this.
How do you handle people wanting to make parallel changes to a record.
Since in web apps you are doing a select, bring over a record then
updating it, there is no lock on that record while you are making the
changes in your browser window. Does transactions handle that? Do you
make your selection and update all part of the same transaction? This
whole scenario has me stumped.
