From time to time customers report the following stack trace when they install an upgrade of my plug-in with PostgreSQL:
This one happened with the following PostgreSQL version:
nameostgreSQL Native Driver
versionostgreSQL 9.4 JDBC4.1 (build 1201)
This normally happens when I add a new column to an entity. In the web I've seen similar issues and normally a restart of the application helps. PostgreSQL seams to have issues with cached plans that have been altered through table changes.
The question is: can you clear those caches in ActiveObjects to circumvent such a restart?
