Ok ... it turns out I was using MyProcPort as a quick way to grab
database_name and user_name (very early in startup, for a purpose
analogous to setting a 'ps' process title), and that seemed mo

Hi,
I have a report of a PL/Java crash in 9.6 where the stack trace
suggests it was trying to initialize in a background worker
