Abstract: We implemented so-called skymaps, i. e., entities representing certain parts of the celestial sphere, as first-class data types within the open source object-relational database management system PostgreSQL, as a) sky coverage objects, following the MOC standard of the International Virtual Observatory Alliance (IVOA), and as b) partial maps of the sky, mapping a set of HEALPix sky elements of a certain resolution to a floating-point value each. We report useful associated analysis functions in the context of a relational database management system, and implementation specifics with respect to PostgreSQL.
