I have two unrelated questions, and I figured I'd be lazy and ask here
instead of running tests myself. :) If there is a FAQ that explains this,
I'd appreciate a pointer to it.
First question: Which types are faster for access: int or char, varchar()
or text? Should I specify a particular type of indexing, or will Postgres
detect the best method?
Second question: If I *don't* use the -F option to cut down on fsync's, is
it safe to backup the database live, or should I still just backup a
pgdumpall? Is there a better way to do it?
