Fix pg_upgrade's multixact handling (again) We need to create the pg_multixact/offsets file deleted by pg_upgrade much earlier than we originally were: it was in TrimMultiXact(), which runs after we exit recovery, but it actually needs to run earlier than the first call to SetMultiXactIdLimit (before recovery), because that routine already wants to read the first offset segment.
Per pg_upgrade trouble report from Jeff Janes. While at it, silence a compiler warning about a pointless assert that an unsigned variable was being tested non-negative. This was a signed constant in Thomas Munro's patch which I changed to unsigned before commit. Pointed out by Andres Freund.
