/* Local file storage allocation chunk.
* Should be power of two. Using larger than page chunks can
* 1. Reduce hash-map memory footprint: 8TB database contains billion pages
* and size of hash entry is 40 bytes, so we need 40Gb just for hash map.
* 1Mb chunks can reduce hash map size to 320Mb.
* 2. Improve access locality, subsequent pages will be allocated together improving seqscan speed
