Could not start the server while major in-place upgrade #969

Open yuniyakim opened 7 months ago

yuniyakim commented 7 months ago

Hello! We're trying to complete a major in-place upgrade of Postgres (from 11 to 12) in a Kubernetes cluster using Zalando Postgres Operator but we keep getting an error when it tries to start the server. The same happens if we try to perform a manual upgrade launching the script with the command python3 /scripts/inplace_upgrade.py 3.

Here is a part of the inplace upgrade logs:

# PostgreSQL configuration file
# -----------------------------
#
# This file consists of lines of the form:
#
#   name = value
#
# (The "=" is optional.)  Whitespace may be used.  Comments are introduced with
# "#" anywhere on a line.  The complete list of parameter names and allowed
# values can be found in the PostgreSQL documentation.
#
# The commented-out settings shown in this file represent the default values.
# Re-commenting a setting is NOT sufficient to revert it to the default value;
# you need to reload the server.
#
# This file is read on server startup and when the server receives a SIGHUP
# signal.  If you edit the file on a running system, you have to SIGHUP the
# server for the changes to take effect, run "pg_ctl reload", or execute
# "SELECT pg_reload_conf()".  Some parameters, which are marked below,
# require a server shutdown and restart to take effect.
#
# Any parameter can also be given as a command-line option to the server, e.g.,
# "postgres -c log_connections=on".  Some parameters can be changed at run time
# with the "SET" SQL command.

# This is used when logging to stderr:

                    # But such truncation only occurs on
                    # time-driven rotation, not on restarts
                    # or size-driven rotation.  Default is

Unfortunately, I am not sure what exactly happened in your case. But maybe this commit fixes the problem Can you re-try using the latest master branch state or the latest Spilo image?
