Abstract: Spherical data appear in a lot of problems in modern science and technology, ranging from geoinformational systems to astronomical catalogues. Efficient handling of such data in Postgres is necessary, and Postgres do have support for it, though not in core, through its ability to define fully indexable custom data types and functional indices. ...

... These are just the bare bones--just three basic ideas and rules for handling relations ("equations") involving unknown quantities whose values you are trying to find. In most calculations you try to find a number . ... To get a solution, one must replace the given equation (or equations) with others, containing the same information but cleaner in appearance. ... If you have an equation and modify both its sides in exactly the same way, what you get is also a valid equation. ...
