pg_stat_replication.sync_state was displayed incorrectly at page boundary. XLogRecPtrIsInvalid() only checks the xrecoff field, which is correct when checking if a WAL record could legally begin at the given position, but WAL sending can legally be paused at a page boundary, in which case xrecoff is 0. Use XLByteEQ(..., InvalidXLogRecPtr) instead, which checks that both xlogid and xrecoff are 0.
9.3 doesn't have this problem because XLogRecPtr is now a single 64-bit integer, so XLogRecPtrIsInvalid() does the right thing. Apply to 9.2, and 9.1 where pg_stat_replication view was introduced.
