Обсуждение: pgsql: Rename asyncCommitLSN to asyncXactLSN to reflect changed role in

Log Message:
-----------
Rename asyncCommitLSN to asyncXactLSN to reflect changed role in 9.0.
Transaction aborts now record their LSN to avoid corner case
behaviour in SR/HS, hence change of name of variables and functions.
As pointed out by Fujii Masao. Cosmetic changes only.
