PostGIS adds support for geographic objects to the PostgreSQL object-relational database. In effect, PostGIS "spatially enables" the PostgreSQL server, allowing it to be used as a backend spatial database for geographic information systems (GIS), much like ESRI's SDE or Oracle's Spatial extension. PostGIS follows the OpenGIS "Simple Features Specification for SQL" and has been certified as compliant with the "Types and Functions" profile.

    FROM prefixes
   WHERE prefix @> '0123456789'
ORDER BY length(prefix::text)
   LIMIT 1;

Texcaller is a convenient interface to the TeX command line tools that handles all kinds of errors without much fuzz. It is written in plain C, is fairly portable, and has no external dependencies besides TeX.

These PostgreSQL functions are simple wrappers around the Texcaller C interface library functions, bringing TeX typesetting into the world of relational databases.

Invalid TeX documents are handled gracefully by simply returning NULL rather than aborting with an error. On failure as well as on success, additional processing information is provided via NOTICEs.

TimeTravel is an added functionality to PostgreSQL which we developed by drawing inspiration from a similar Oracle functionality: FlashBack. Since human errors are among the first causes of data loss, it would be a good idea to maintain historical details of all transactions, for a limited time, to be able to rollback a committed transactions when it will be needed.
