Decription in jira issue PBCKP-236
|

This test exposures ticket error using pg_probackup builds for both PGPROEE11 and PGPROEE9_6
|
|
|
|
Prerequisites:
|
|
- pg_probackup git tag for PBCKP 2.5.1
|
|
- master pg_probackup build should be made for PGPROEE11
|
|
- agent pg_probackup build should be made for PGPROEE9_6
|
|
|
|
Calling probackup PGPROEE9_6 pg_probackup agent from PGPROEE11 pg_probackup master for DELTA backup causes
|
|
the PBCKP-236 problem
|
|
|
|
Please give env variables PROBACKUP_MANUAL=ON;PGPROBACKUP_SSH_AGENT_PATH=<pg_probackup_ssh_agent_path>
|
|
for the test
|
|
|
|
Please make path for agent's pgprobackup_ssh_agent_path = '/home/avaness/postgres/postgres.build.ee.9.6/bin/'

without pg_probackup executable
