ZSON just replaces frequently used strings to 16-bit codes. It also adds
PGLZ_HINT_SIZE (=32 by default, could be also 0) zero bytes in the
beginning to make it more likely that data will be compressed using PGLZ.
After all, who will use ZSON for small documents? Thats all.
Hope it explains references to PGLZ.
