OK, I know what happen.
It seems like your standbies were not replicating when the master "crashed",
you can find tons of messages like this in the log files:
WARNING: No secondary connected to the master
WARNING: "db2" is not connected to the primary
WARNING: "db3" is not connected to the primary
When a standby is not replicating, the master set negative master score to them
to forbid the promotion on them, as they are probably lagging for some
The following command shows the scores just before the simulated master crash:
$ crm_simulate -x pe-input-2039.bz2 -s|grep -E 'date|promotion'
Using the original execution date of: 2018-04-11 16:23:07Z
pgsqld:0 promotion score on db1: 1001
pgsqld:1 promotion score on db2: -1000
pgsqld:2 promotion score on db3: -1000
"1001" score design the master. Streaming standbies always have a
positive master score between 1000 and 1000-N*10 where N is the number of
