logical replication issue

I am upgrading our existing 12.22 Aurora Postgresql clusters to 16.8 using: https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/AuroraPostgreSQL.MajorVersionUpgrade.html

I have created a pub sub replication with a slot per database. I originally created 1 publication for each database for all tables. Due to this appeared issue, I have changed that method to creating 1 publication per schema. This allows limiting a smaller set of tables from the subscription. 

Either way getting errors: 

2025-04-16 18:47:11 UTC::@:[1633]:LOG: logical replication apply worker for subscription "clone_rep_slot_cdc_only_sub" has started

2025-04-16 18:47:12 UTC::@:[1633]:ERROR: could not identify an equality operator for type xml 

2025-04-16 18:47:12 UTC::@:[1633]:CONTEXT: processing remote data for replication origin "pg_2141834" during message type "UPDATE" for replication target relation "sde.gdb_items" in transaction 151772192, finished at 0/61601498 

2025-04-16 18:47:12 UTC::@:[569]:LOG: background worker "logical replication worker" (PID 1633) exited with exit code 1 

 It appears to be failing on the gdb_items table because there are columns of datatype xml. The only way I could get this to run was to exclude tables from the sde schema with datatype xml in the schema publication. Or remove the entire schema publication from the subscription. Once I remove the table(s) in question the slot becomes active.

Is this an undocumented limitation? I cannot find this limitation anywhere, in aws docs: https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/blue-green-deployments-considerations.html#blue-green-deployments-limitations-postgres-logical

Nor in Postgresql version 16: https://www.postgresql.org/docs/16/logical-replication-restrictions.html

Should logical replication fail due to a column of type 'xml' in a table in a publication?

I assume this issue in replication is related to this excerpt from docs:
