when trying to apply my plan i get this error,

 Error: pq: apg_plan_mgmt not in shared_preload_libraries

however, when i add it at as a param to my cluster like so

  parameter {
    name         = "shared_preload_libraries"
    value        = "apg_plan_mgmt,pg_stat_statements"
    apply_method = "pending-reboot"
  }

i get the error

Terraform v1.6.2
on linux_amd64

aws_rds_cluster_parameter_group.qpm_cluster_parameter_group: Creating...

How can I add apg_plan_mgmt library to the preloaded libs? I’d like to use it through terraform, but not sure if there is a sequence I need to follow in order to load it

I see from here

Terraform & RDS Postgres: why isn’t pg_repack allowed in shared_preload_libraries? that I just need to create the extension, however when trying that, i got the original error
