I'm not sure there's any underlying issue here, except being in single user mode. > When I try it, I get a > > TRAP: FailedAssertion("!(event->fd != (-1))", File: "latch.c", Line: 861) > > which might indicate that there is a more general problem with latch use > in single-user mode. That just means that the latch isn't initialized. Which makes: > If I remove that assertion, things work fine after that.

I'm not sure how this hints at platform dependent behaviour? libpqrcv_connect() uses MyProc->procLatch, which doesn't exist/isn't initialized in single user mode. I'm very unclear why that code uses MyProc->procLatch rather than MyLatch, but that'd not change anything - the tablesync stuff etc would still not work. - Andres -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
