After updating a database from Postgres 9.6 to 10 all applications stopped working. The error message in the server log file is “Unable to load requested class: pg-uuid”.
PGModeler (http://www.pgmodeler.com.br) is a nice tool to design your (PostgreSQL) database. It supports import from and export to a databases. Ubuntu 15.10 comes with a quite recent version but e.g. Debian does not provide it in the repository. In this post I explain howto build the application on Linux (tested on Debian 8) from source.
