Hi list To make inspecting PostGIS tables in psql easier I have written a function which outputs PostGIS Geometry objects as a string of ASCII art. Please does anyone know if there is there some way I can have my function called automatically by psql instead of me writing it into the query each time? E.g. a user defined \pset option or some sort of extension API which gives me access to the print logic or 'presentation layer' of psql. By 'automatically' I mean through association with the PostGIS geometry types. Example of how it looks at the moment: https://hastebin.com/nihujociga.sql Kind regards Peter
