Bug 1862169

Description of problem:
When running the log-collector, when it gets to the step of:"Gathering PostgreSQL the oVirt Engine database and log files from localhost" it returns the following error:
ERROR: Could not collect PostgreSQL information: [Errno 2] No such file or directory: '/tmp/logcollector-7gp51cfp/working/log-collector-data/sosreport-Z-Z-Z-Z-2020-07-30-wetccry.tar.xz.sha256' -> '/tmp/logcollector-7gp51cfp/working/log-collector-data/postgresql-sosreport-Z-Z-Z-Z-2020-07-30-wetccry.tar.xz.sha256'

However the workflow continues and log-collector prompts if user wants to continue to collect information about X hosts and replying with Y, it succeeds.
