Hmm, I just apply v13 patch but failed.
Part of errors:
```
error: patch failed: contrib/pg_buffercache/pg_buffercache.control:1 error: contrib/pg_buffercache/pg_buffercache.control: patch does not apply
Checking patch contrib/pg_buffercache/pg_buffercache_pages.c...
error: while searching for:
*/
PG_FUNCTION_INFO_V1(pg_buffercache_pages);
PG_FUNCTION_INFO_V1(pg_buffercache_pages_v1_4);
```
Rebase on master and then apply our changes again?
