I am currently upgrading a Postgres cluster running on a Centos machine
from version 9.6.22 to 12.7. Post the install of 12.7 binaries, I am
running the pg_upgrade command:
/usr/pgsql-12/bin/pg_upgrade -b /usr/pgsql-9.6/bin/ -B /usr/pgsql-12/bin/
-d /<path>/9.6/data.old -D /<path>/12/data/ -j 12 -r -v -k
But, I am getting multiple errors during the "Restoring database schemas in
the new cluster" step:
pg_restore: creating TABLE "schema1.table1"
pg_restore: creating TABLE "schema1.table2"
pg_restore: creating TABLE "schema1.table3"
pg_restore: while PROCESSING TOC:
pg_restore: from TOC entry 358; 1259 793395 TABLE table3 postgres
pg_restore: error: could not execute query: FATAL: terminating
connection due to administrator command
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
Command was:-- For binary upgrade, must preserve pg_type oidSELECT
pg_catalog.binary_upgrade_set_next_pg_type_oid('793397'::pg_catalog.oid);

Restore command from the logs:
"/usr/pgsql-12/bin/pg_restore" --host /var/lib/pgsql --port 50432
--username postgres --create --exit-on-error --verbose --dbname
template1 "pg_upgrade_dump_16405.custom" >>
"pg_upgrade_dump_16405.log" 2>&1
Similarly, at each run a different dump file fails (
pg_upgrade_dump_16405.custom/pg_upgrade_dump_16404.custom). Has anyone
faced similar issues during upgrade to Postgres 12.7?
There isn't much in the pg_upgrade_server.log file. It looks like the
server starts and stops for the old and new data files.
pg_upgrade_server.log file - textuploader.com/ta9o3
Under /<path>/12/data/log. I see these lines:
```
LOG: background worker "logical replication launcher" (PID 35687) exited
with exit code 1
LOG: shutting down
LOG: database system is shut down
LOG: database system was shut down at 2021-07-30 01:33:51 GMT
LOG: database system is ready to accept connections ERROR: relation
"sequence2" already exists
```
I am getting an error even after only initDB and running upgrade. Any
suggestions on what could be going wrong?
Thanks in advance!
