Optimize nbtree backwards scans.
Make nbtree backwards scans optimistically access the next page to be
read to the left by following a prevPage block number that's now stashed
in currPos when the leaf page is first read. This approach matches the
one taken during forward scans, which follow a sym
Disable autovacuum for tables in stats import tests.
While we haven't observed any test instability, it seems like a good
idea to disable autovacuum during the stats import tests.

Adjust documentation for configuring Linux huge pages.
The present wording about viewing shared_memory_size_in_huge_pages
seems to suggest that the parameter cannot be viewed after startup
at all, whereas the intent is to make it clear that you can't use
"postgres -C" to view this parameter while

Allow pg_set_relation_stats() to set relpages to -1.
While the default value for relpages is 0, if a partitioned table with
at least one child has been analyzed, then the partititoned table will
have a relpages value of -1.

Remove unused code for unlogged materialized views.
Commit 3bf3ab8c56 initially introduced support for unlogged
materialized views, but this was later disallowed by commit 3223b25ff7.
Additionally, commit d25f519107 added more code for handling
unlogged materialized views. This commit cleans up al
Fix memory leaks from incorrect strsep() uses
Commit 5d2e1cc117b introduced some strsep() uses, but it did the
memory management wrong in some cases. We need to keep a separate
pointer to the allocate memory so that we can free it later, because
strsep() advances the pointer we pass to it, and it
Fix strsep() use for SCRAM secrets parsing
The previous code (from commit 5d2e1cc117b) did not detect end of
string correctly, so it would fail to error out if fewer than the
expected number of fields were present, which could then later lead to
a crash when NULL string pointers are accessed.
