This is the new assertion in pg_atomic_monotonic_advance_u64() and therefore the only possible culprit could be logInsertResult in XLogCtlData. Does it work if you do this? diff --git a/src/backend/access/transam/xlog.c b/src/backend/access/transam/xlog.c index 8dcdf5a764..e581488d57 100644 --- a/src/backend/access/transam/xlog.c +++ b/src/backend/access/transam/xlog.c @@ -468,7 +468,7 @@ typedef struct XLogCtlData XLogRecPtr lastSegSwitchLSN; /* These are accessed using atomics -- info_lck not needed */ - pg_atomic_uint64 logInsertResult; /* last byte + 1 inserted to buffers */ + pg_atomic_uint64 logInsertResult pg_attribute_aligned(8); /* last byte + 1 inserted to buffers */ pg_atomic_uint64 logWriteResult; /* last byte + 1 written out */ pg_atomic_uint64 logFlushResult; /* last byte + 1 flushed */ Thanks -- Álvaro Herrera PostgreSQL Developer — https://www.EnterpriseDB.com/ "Use it up, wear it out, make it do, or do without"
