Eliminate XLOG_HEAP2_VISIBLE from vacuum phase III
Instead of emitting a separate XLOG_HEAP2_VISIBLE WAL record for each
page that becomes all-visible in vacuum's third phase, specify the VM
changes in the already emitted XLOG_HEAP2_PRUNE_VACUUM_CLEANUP record.
Visibility checks are now performed
Fix incorrect message-printing in win32security.c.
log_error() would probably fail completely if used, and would
certainly print garbage for anything that needed to be interpolated
into the message, because it was failing to use the correct printing
subroutine for a va_list argument.

Remove state.tmp when failing to save a replication slot
An error happening while a slot data is saved on disk in
SaveSlotToPath() could cause a state.tmp file (temporary file holding
the slot state data, renamed to its permanent name at the end of the
function) to remain around after it has been
Fix serious performance problems in LZ4Stream_read_internal.
I was distressed to find that reading an LZ4-compressed toc.dat
file was hundreds of times slower than it ought to be. On
investigation, the blame mostly affixes to LZ4Stream_read_overflow's
habit of memmove'ing all the remaining buffer
Fix version number calculation for data folder flush in pg_combinebackup
The version number calculated by read_pg_version_file() is multiplied
once by 1, to be able to do comparisons based on PG_VERSION_NUM or
equivalents with a minor version included. However, the version number

Doc: clarify n_distinct_inherited setting
There was some confusion around how to adjust the n_distinct estimates
for partitioned tables. Here we try and clarify that
n_distinct_inherited needs to be adjusted rather than n_distinct.

Fix issue with reading zero bytes in Gzip_read.
pg_dump expects a read request of zero bytes to be a no-op; see for
example ReadStr(). Gzip_read got this wrong and falsely supposed
that the resulting gzret == 0 indicated an error. We could complicate
that error-checking logic some more, but it s
Fix poor buffering logic in pg_dump's lz4 and zstd compression code.
Both of these modules dumped each bit of output that they got from
the underlying compression library as a separate "data block" in
the emitted archive file. In the case of zstd this'd frequently
result in block sizes well under
