Thanks for updating the patch!
+ printf(_(" -x, --xid=XID only show records with transaction
ID XID\n"));
I think the description of transaction ID is enough, IIUC, XID is use in core,
which means transaction ID.
See: src/bin/pg_resetwal/pg_resetwal.c
1239 printf(_(" -V, --version output version
information, then exit\n"));
1240 printf(_(" -x, --next-transaction-id=XID set next transaction
ID\n"));

!OidIsValid(config.filter_by_relation.spcNode) ||

!OidIsValid(config.filter_by_relation.relNode))
It seems we should also check the dbNode.
