    You do NOT need to call pg_free_result() on every result resource you create.
    When result resources go out of scope, they are garbage collected just like everything else.
    Unless you're hoarding your results somewhere, you can basically ignore this function.

    Here's a little test you can run to confirm this: http://pastebin.com/ghw1PHuE
