  1. Report oldest xmin source when autovacuum cannot remove tuples 

    Autovacuum logging now tells which backend or mechanism kept OldestXmin
from advancing when dead tuples remain, improving diagnosis of bloating
and wraparound hazards. ProcArray now records an OldestXminSource for
each computed horizon, and VACUUM retrieves it through the new
GetOldestNonRemovableTransactionIdWithReason() helper. The log output
names active transactions (with pid), hot standby feedback, prepared
transactions, replication slots, or otherwise labels the cause as
"other".
