Hello All,

we are facing below issues while upgrading the cluster from 12.7 to 15.2.

The OLD cluster contains cstore_fdw extension and we have installed Citus(updated version of cstore_fdw) in postgresql 15.2 , we are not able to proceed further as the below error is the blocker for the same, any help regarding this will be much helpful.

TESTHOST:/tmp $ $NEW_PG_PATH/bin/pg_upgrade -b $OLD_PG_PATH/bin/ -B $NEW_PG_PATH/bin/   -d $OLD_PG_DATA -D $NEW_PG_DATA --check

Thanks,

I'd imagine you cannot have the extension pre-created in the new cluster before the upgrade proceeds. Especially if it's a newer version. You may have to do the upgrade with the old version of the extension installed and then update to the new version after the PG upgrade.

If you don't get any further responses on this list, it may be better to try and contact Citus for further support or make an issue on their github - https://github.com/citusdata/cstore_fdw/issues
