value-to-be-compressed. (first_success_by is 1024 in the default set of compression parameters.)
Curious idea: we could swap JEntry array and values: values in the begining of type will be catched by pg_lzcompress. But we will need to know offset of JEntry array, so header will grow up till 8 bytes (actually, it will be a varlena header!)
