Add some comments to some SQL features
Otherwise, it could be confusing to a reader that some of these
well-publicized features are simply listed as unsupported without
further explanation.

doc: clarify hierarchy of objects: global, db, schema, etc.
The previous wording was confusing because it wasn't in decreasing order
and had to backtrack. Also clarify role/user wording.

Allow parallel vacuum to accumulate buffer usage.
Commit 40d964ec99 allowed vacuum command to process indexes in parallel but
forgot to accumulate the buffer usage stats of parallel workers. This
allows leader backend to accumulate buffer usage stats of all the parallel
workers.

Collect statistics about SLRU caches
There's a number of SLRU caches used to access important data like clog,
commit timestamps, multixact, asynchronous notifications, etc. Until now
we had no easy way to monitor these shared caches, compute hit ratios,
number of reads/writes etc.
This commit ext
Clean up parsing of ltree and lquery some more.
Fix lquery parsing to handle repeated flag characters correctly,
and to enforce the max label length correctly in some cases where
it did not before, and to detect empty labels in some cases where
it did not before.
In a more cosmetic vein, use a sw
Add support for binary I/O of ltree, lquery, and ltxtquery types.
Not much to say here --- does what it says on the tin. The "binary"
representation in each case is really just the same as the text format,
though we prefix a version-number byte in case anyone ever feels
motivated to change that.

Improve selectivity estimation for assorted match-style operators.
Quite a few matching operators such as JSONB's @> used "contsel" and
"contjoinsel" as their selectivity estimators. That was a bad idea,
because (a) contsel is only a stub, yielding a fixed default estimate,
and (b) that default i

Update SQL features count
The previously listed total of 179 does not appear to be correct for
SQL:2016 anymore. (Previous SQL versions had slightly different
feature sets, so it's plausible that it was once correct.) The
currently correct count is the number of rows in the respective tables

Correct CREATE INDEX documentation for opclass parameters
Old versions of opclass parameters patch supported ability to specify DEFAULT
