v14 has already bitrot, so I'm posting this new v15 to keep the
patchset applying cleanly.

There is one new patch in v15:
v15-0007-Add-UnlockBufferGetLSN-utility-function.patch. This adds a
new utility function to bufmgr.c, which combines the functionality of
BufferGetLSNAtomic with UnlockReleaseBuffer. This microoptimization is
intended to avoid regressions against master with workloads like
pgbench SELECT. With this, we're slightly faster than the master
branch on these workloads.
