Postgres Dynamic Credentials with Pgpool

We leverage pgpool-II in our environment for connection pooling and HA for Postgres. We would like to enable Vault dynamic credentials but have run into a problem where the dynamic credential is updated in Postgres, but not in Pgpool’s pool_passwd file. Have others been able to use dynamic credentials with this type of setup? Are others using a different tech stack for pooling, ha, replication, failover, etc that works more favorably with Vault?
