Oh, to clarify: I misread "get_database_list()" as "get_subscription_list()", which is the part of the LR launcher startup that causes the problem for me. So what we actually have confirmed is that BOTH of those launchers are problematic for this. And AFAICS neither of them needs to be causing horizon adjustments for non-shared tables. (It's possible that the AV launcher is responsible in some of wrasse's reports, but it's been the LR launcher in five out of five sufficiently-instrumented failures for me.) regards, tom lane
