State explicitly that the coordinates in our geometric data types are float8. Also explain that polygons store their bounding box. While here, fix the table of geometric data types to show type "line"'s size correctly: it's 24 bytes not 32. This has somehow escaped notice since that table was made in 1998. Per suggestion from Sebastian Skałacki. The size error seems important enough to justify back-patching. Discussion: https://postgr.es/m/172000045661.706.1822177575291548794@wrigleys.postgresql.org
