This does not affect any <backrest/> functionality, but the convenience link <path>latest</path> will not be created and neither will internal tablespace symlinks, which will affect the ability to bring up clusters in-place manually using filesystem snapshots.</p>

+pageChecksum.c
+
+Checksum implementation for data pages.
+
+Portions Copyright (c) 1996-2016, PostgreSQL Global Development Group
+Portions Copyright (c) 1994, Regents of the University of California
+
+Copied from src/include/storage/checksum_impl.h in the PostgreSQL project.
+
+The algorithm used to checksum pages is chosen for very fast calculation. Workloads where the database working set fits into OS file
+cache but not into shared buffers can read in pages at a very fast pace and the checksum algorithm itself can become the largest
+bottleneck.
+
+The checksum algorithm itself is based on the FNV-1a hash (FNV is shorthand for Fowler/Noll/Vo).  The primitive of a plain FNV-1a
+hash folds in data 1 byte at a time according to the formula:
+
+    hash = (hash ^ value) * FNV_PRIME
+
+FNV-1a algorithm is described at http://www.isthe.com/chongo/tech/comp/fnv/
+
+PostgreSQL doesn't use FNV-1a hash directly because it has bad mixing of high bits - high order bits in input data only affect high
+order bits in output data. To resolve this we xor in the value prior to multiplication shifted right by 17 bits. The number 17 was
+chosen because it doesn't have common denominator with set bit positions in FNV_PRIME and empirically provides the fastest mixing
+for high order bits of final iterations quickly avalanche into lower positions. For performance reasons we choose to combine 4 bytes
+at a time. The actual hash formula used as the basis is:
+
+    hash = (hash ^ value) * FNV_PRIME ^ ((hash ^ value) >> 17)
+
+The main bottleneck in this calculation is the multiplication latency. To hide the latency and to make use of SIMD parallelism
+multiple hash values are calculated in parallel. The page is treated as a 32 column two dimensional array of 32 bit values. Each
+column is aggregated separately into a partial checksum. Each partial checksum uses a different initial value (offset basis in FNV
+terminology). The initial values actually used were chosen randomly, as the values themselves don't matter as much as that they are
+different and don't match anything in real data. After initializing partial checksums each value in the column is aggregated
+according to the above formula. Finally two more iterations of the formula are performed with value 0 to mix the bits of the last
+value added.
+
+The partial checksums are then folded together using xor to form a single 32-bit checksum. The caller can safely reduce the value to
+16 bits using modulo 2^16-1. That will cause a very slight bias towards lower values but this is not significant for the performance
+of the checksum.
+
+The algorithm choice was based on what instructions are available in SIMD instruction sets. This meant that a fast and good
+algorithm needed to use multiplication as the main mixing operator. The simplest multiplication based checksum primitive is the one
+used by FNV. The prime used is chosen for good dispersion of values. It has no known simple patterns that result in collisions. Test
+of 5-bit differentials of the primitive over 64bit keys reveals no differentials with 3 or more values out of 100000 random keys
+colliding. Avalanche test shows that only high order bits of the last word have a bias. Tests of 1-4 uncorrelated bit errors, stray
+0 and 0xFF bytes, overwriting page from random position to end with 0 bytes, and overwriting random segments of page with 0x00, 0xFF
+and random data all show optimal 2e-16 false positive rate within margin of error.
+
+Vectorization of the algorithm requires 32bit x 32bit -> 32bit integer multiplication instruction. As of 2013 the corresponding
+instruction is available on x86 SSE4.1 extensions (pmulld) and ARM NEON (vmul.i32). Vectorization requires a compiler to do the
+vectorization for us. For recent GCC versions the flags -msse4.1 -funroll-loops -ftree-vectorize are enough to achieve
+vectorization.
+
+The optimal amount of parallelism to use depends on CPU specific instruction latency, SIMD instruction width, throughput and the
+amount of registers available to hold intermediate state. Generally, more parallelism is better up to the point that state doesn't
+fit in registers and extra load-store instructions are needed to swap values in/out. The number chosen is a fixed part of the
+algorithm because changing the parallelism changes the checksum result.
+
+The parallelism number 32 was chosen based on the fact that it is the largest state that fits into architecturally visible x86 SSE
+registers while leaving some free registers for intermediate values. For future processors with 256bit vector registers this will
+leave some performance on the table. When vectorization is not available it might be beneficial to restructure the computation to
+calculate a subset of the columns at a time and perform multiple passes to avoid register spilling. This optimization opportunity
+is not used. Current coding also assumes that the compiler has the ability to unroll the inner loop to avoid loop overhead and
+minimize register spilling. For less sophisticated compilers it might be beneficial to manually unroll the inner loop.
