Assign AccessExclusiveLocks against subxacts in Hot Standby Previously AELs were registered against the top-level xid, which could cause locks to be held much longer than necessary in some cases during Hot Standby replay. We now record locks directly against their appropriate xids. Requires few code changes because original code allowed for this situation but didn’t fully implement it.
