Thread: Pg Upgrade failing as it is not able to start and stop server properly

Hi, 

While upgrading the PostgreSQL database from 9.1.4 to 9.6.4 version on windows 2012 server, Pg_upgrade is failing as postgre service start and stop are failing because of time outs. I got the information as using -m immediate mode with solve the problem, but we are interested to know the root cause of this issue.

Without -m immediate, the server start and stop commands will simply wait, till command timeouts and they fail.

There is no load on the server that could cause a performance issue. 

Below is the failure snippet from pg_upgrade_internal.log file.

Checking for presence of required libraries                 ok

Checking database user is the install user                  executing: SELECT rolsuper, oid FROM pg_catalog.pg_roles WHERE rolname = current_user AND rolname !~ '^pg_'

executing: SELECT COUNT(*) FROM pg_catalog.pg_roles WHERE rolname !~ '^pg_'

ok

Checking for prepared transactions                          executing: SELECT * FROM pg_catalog.pg_prepared_xacts

ok

If pg_upgrade fails after this point, you must re-initdb the

new cluster before continuing.

Performing Upgrade

------------------

Analyzing all rows in the new cluster                       "c:\EMC\AppSync\jboss\datastore_96\engine\bin/vacuumdb" --port 50432 --username ^"apollosuperuser^" --all --analyze --verbose >> "pg_upgrade_utility.log" 2>&1

ok

Freezing all rows on the new cluster                        "c:\EMC\AppSync\jboss\datastore_96\engine\bin/vacuumdb" --port 50432 --username ^"apollosuperuser^" --all --freeze --verbose >> "pg_upgrade_utility.log" 2>&1

*failure*

"c:\EMC\AppSync\jboss\datastore_96\engine\bin/pg_ctl" -w -D "c:\EMC\AppSync\jboss\datastore_96\data" -o "" -m fast stop >> "pg_upgrade_utility.log" 2>&1

Below are the pg_upgrade logs pertaining to the failure. Please suggest any solutions to fix this issue.

It appears the freeze operation is failing, and I have no idea what
would cause that.
