I googled "plpgsql debugger" and eventually ended up at http://pgfoundry.org/projects/edb-debugger/, where the latest release is almost 8 years old. I am aware that this is not an EDB forum but given that I sent them an e-mail at 9AM EST and I haven't received a response yet I figured it can't hurt to try my question here. Is anyone using it on recent (e.g., 9.5) versions of PostgreSQL. If not, is there any consensus on what one should be using to debug PL/pgSQL functions?
plpgsql debugger should be included directly in pgAdminIII
The necessary extension can 8 years old - it implements communication between client and server side code and this is long time without change
