Hi,
I realized that standby_desc_running_xacts() in standbydesc.c doesn't
describe subtransaction XIDs. I've attached the patch to improve the
description. Here is an example by pg_wlaldump:
* HEAD
rmgr: Standby len (rec/tot): 58/ 58, tx: 0, lsn:
0/01D0C608, prev 0/01D0C5D8, desc: RUNNING_XACTS nextXid 1050
latestCompletedXid 1047 oldestRunningXid 1048; 1 xacts: 1048
* w/ patch
rmgr: Standby len (rec/tot): 58/ 58, tx: 0, lsn:
0/01D0C608, prev 0/01D0C5D8, desc: RUNNING_XACTS nextXid 1050
latestCompletedXid 1047 oldestRunningXid 1048; 1 xacts: 1048; 1
subxacts: 1049
Please review it.
Regards,
