Hi,

Is this patch target to PG16 now?

I want to have a look at these patches, but apply on master failed:

Applying: Use 64-bit numbering of SLRU pages.
Applying: Use 64-bit format to output XIDs
Applying: Use 64-bit FullTransactionId instead of Epoch:xid
Applying: Use 64-bit pages representation in SLRU callers.
error: patch failed: src/backend/access/transam/multixact.c:1228
error: src/backend/access/transam/multixact.c: patch does not apply
Patch failed at 0004 Use 64-bit pages representation in SLRU callers.
hint: Use 'git am --show-current-patch=diff' to see the failed patch
