1/7/2024 0 Comments Aurora postgresql![]() ![]() Notice how I renamed DBParamGroup to DBParamGroup11 and DBClusterParamGroup to DBClusterParamGroup11. #trying to change to 'aurora-postgresql11'ĭescription: !Sub 'AuroraDBClusterParamGroup-$'ĭBClusterParameterGroupName: !Ref 'DBClusterParamGroup'ĭBParameterGroupName: !Ref 'DBParamGroup'ĭBClusterIdentifier: !Ref 'AuroraDBCluster' Now the database is updated, it is using the custom parameter groups, and the stack is not drifting Uncomment out the code for DBClusterParameterGroup and DBParameterGroup and update the stack again with the correct Family property aurora-postgresql11 on DBClusterParameterGroup and DBParameterGroup.Comment out the code for DBClusterParameterGroup and DBParameterGroup and update the stack with the updated EngineVersion 11.9 for DBCluster.Manually update the database version in the console from 10.14 to 11.9, and change the DB cluster parameter group and Parameter group both to rora-postgresql11 as well.The only workaround I have found is clunky: Set up an AWS DMS environment including replication server, and fine-tune data migration. Perform database schema migration to Aurora using the native PostgreSQL tool. Set up the target Aurora environment based on the target Aurora PostgreSQL. Got error "Unmodifiable DB Parameter: pg_bigm.last_update" At a high level, our approach included the following steps: Enable the source database to support DMS. Manually adding the parameters listed in the error to DBParameterGroup before running update.Says that will trigger a Replacement, but it does not actually do So even though I am trying to update the Family property for DBClusterParameterGroup and DBParameterGroup, CloudFormation simply ignores that, and so it is trying to apply the aurora-postgresql10 Parameter group Family aurora-postgresql10 to a database now trying to run Aurora Postgres 11.9 What I've triedĭBClusterParameterGroup andDBParameterGroup to include a reference to thepEngineVersion` parameter, as the AWS Documentation The DB cluster parameter group family can't be changed when updating a DB cluster parameter group I think this is because, according to the AWS Documentation for RDS Parameter Groups: The following parameters are not defined for the specified group: enable_partitionwise_aggregate, enable_parallel_append, enable_partition_pruning, vacuum_cleanup_index_scale_factor, pg_bigm.last_update, apg_enable_semijoin_push_down, parallel_leader_participation, pg_bigm.enable_recheck, pg_bigm.gin_key_limit, max_parallel_maintenance_workers, pg_bigm.similarity_limit, enable_parallel_hash, enable_partitionwise_join (Service: AmazonRDS Status Code: 400 Error Code: InvalidParameterValue) The problem is that when I try to update the stack and change the EngineVersion property for DBCluster from 10.14 to 11.9 and change the Family property for DBClusterParameterGroup and DBParameterGroup from aurora-postgresql10 to aurora-postgresql11, I get this error in CloudFormation: Error My template creates a DBCluster, a DBInstance, a DBClusterParameterGroup and a DBParameterGroup. I am trying to do a major version upgrade from Aurora Postgres 10.14 to 11.9 using Cloudformation.
