Thanks for addressing my previous review comments. I re-checked the latest patch v12-0001 and found the following:
====== Commit message 1. The new SQL binary_upgrade_create_sub_rel_state function has the following syntax: SELECT binary_upgrade_create_sub_rel_state(subname text, relid oid, state char [,sublsn pg_lsn]) ~ Looks like v12 accidentally forgot to update this to the modified function name 'binary_upgrade_add_sub_rel_state' ====== Kind Regards, Peter Smith.
