Well I tried your steps, both Postgres 10 and 12 are in perfect running
conditions and were shut down using the "systemctl" command. When I execute:
/usr/pgsql-12/bin/pg_upgrade --old-bindir=/usr/pgsql-10/bin/
--new-bindir=/usr/pgsql-12/bin/ --old-datadir=/var/lib/pgsql/10/data
--new-datadir=/var/lib/pgsql/12/data --old-options '-c
config_file=/var/lib/pgsql/10/data/postgresql.conf' --new-options '-c
config_file=/var/lib/pgsql/12/data/postgresql.conf' --check
I get:
Performing Consistency Checks
-----------------------------
Checking cluster versions ok
Checking database user is the install user ok
Checking database connection settings ok
Checking for prepared transactions ok
Checking for reg* data types in user tables ok
Checking for contrib/isn with bigint-passing mismatch ok
Checking for tables WITH OIDS ok
Checking for invalid "sql_identifier" user columns ok
Checking for presence of required libraries ok
Checking database user is the install user ok
Checking for prepared transactions ok
*Clusters are compatible*
But if I execute the same command right after that without the "--check"
flag I get:
Performing Consistency Checks
-----------------------------
Checking cluster versions ok
The target cluster was not shut down cleanly.
Failure, exiting
Both of the servers were still shut down. If I start form the beginning with
a fresh Prostgres 12 installation and execute the upgrade command right away
without the "--check" flag I get the problem described in my original post.
Best regards,
