   Thank you so much for your explanation! When the `Compress()` function is called:
   
   1. From `WriteDataPage(page)`: In case the page is being compressed, the source buffer size is 20 for each column (makes sense, sinve 5 int32s = 20 bytes)
   2. From `pager_->has_compressor()`: What exactly is being compressed? The source buffer size is mostly an odd number and in the example above, the source buffer size is 11 bytes. Could you please shed some light on this?
