System catalogs and views should be listed alphabetically
in catalog.sgml, but only pg_file_settings view not.
This patch also fixes typos in pg_file_settings comments.
Following recent discussion on -hackers. The underlying function is
also renamed to jsonb_delete_path. The regression tests now don't need
ugly type casts to avoid the ambiguity, so they are also removed.
Catalog version bumped.
Supporting deletion of JSON pairs within jsonb objects using an
array-style integer subscript allowed for surprising outcomes. This was
mostly due to the implementation-defined ordering of pairs within
objects for jsonb.
It also seems desirable to make jsonb integer subscript deletion
consistent with the 9.4 era general purpose integer subscripting
operator for jsonb (although that operator returns NULL when an object
is encountered, while we prefer here to throw an error).
Peter Geoghegan, following discussion on -hackers.
Materialized views and foreign tables were missing from the list,
probably because they are newer than the other object types that were
mentioned.

The commit c22ed3d523 turned
the -i/--ignore-version options into no-ops and marked as deprecated.
Considering we shipped that in 8.4, it's time to remove all trace of
those switches, per discussion. We'd still have to wait a couple releases
before it'd be safe to use -i for something else, but it'd be a start.
- Correct the name of directory which those catalog columns allow to be shrunk.
- Correct the name of symbol which is used as the value of pg_class.relminmxid
when the relation is not a table.
- Fix "ID ID" typo.
Backpatch to 9.3 where those cataog columns were introduced.
Because of a bug in the DocBook XSL FO style sheet, an xref to a
varlistentry whose term includes an indexterm fails to build. One such
instance was introduced in commit
5086dfceba. Fix by adding the upstream
bug fix to our customization layer.
Also sneak entries for commits 97ff2a564 et al into the sections for
the previous releases in the relevant branches. Those fixes did go out
in the previous releases, but missed getting documented.
The function is given a fourth parameter, which defaults to true. When
this parameter is true, if the last element of the path is missing
in the original json, jsonb_set creates it in the result and assigns it
the new value. If it is false then the function does nothing unless all
elements of the path are present, including the last.
Based on some original code from Dmitry Dolgov, heavily modified by me.
Catalog version bumped.
The existing documentation could easily be misinterpreted, and it failed to
explain the inconsistent-evaluation hazard that deterred us from supporting
automatic importing of check constraints. Revise it.
Etsuro Fujita, further expanded by me
Remove a bunch of "extern Datum foo(PG_FUNCTION_ARGS);" declarations that
are no longer needed now that PG_FUNCTION_INFO_V1(foo) provides that.
Some of these were evidently missed in commit e7128e8dbb, but others
were cargo-culted in in code added since then. Possibly that can be blamed
in part on the fact that we'd not fixed relevant documentation examples,
which I've now done.
Fix confusion in documentation, substantial memory leakage if float8 or
float4 are pass-by-reference, and assorted comments that were obsoleted
by commit 98edd617f3.
Previously, INSERT with ON CONFLICT DO UPDATE specified used a new
command tag -- UPSERT. It was introduced out of concern that INSERT as
a command tag would be a misrepresentation for ON CONFLICT DO UPDATE, as
some affected rows may actually have been updated.
Alvaro Herrera noticed that the implementation of that new command tag
was incomplete; in subsequent discussion we concluded that having it
doesn't provide benefits that are in line with the compatibility breaks
it requires.
Catversion bump due to the removal of PlannedStmt->isUpsert.

Use "a" and "an" correctly, mostly in comments. Two error messages were
also fixed (they were just elogs, so no translation work required). Two
function comments in pg_proc.h were also fixed. Etsuro Fujita reported one
of these, but I found a lot more with grep.
Also fix a few other typos spotted while grepping for the a/an typos.
For example, "consists out of ..." -> "consists of ...". Plus a "though"/
"through" mixup reported by Euler Taveira.
Many of these typos were in old code, which would be nice to backpatch to
make future backpatching easier. But much of the code was new, and I didn't
feel like crafting separate patches for each branch. So no backpatching.
These were "text", but that's a bad idea because it has collation-dependent
ordering. No index in template0 should have collation-dependent ordering,
especially not indexes on shared catalogs. There was general agreement
that provider names don't need to be longer than other identifiers, so we
can fix this at a small waste of table space by changing from text to name.
There's no way to fix the problem in the back branches, but we can hope
that security labels don't yet have widespread-enough usage to make it
urgent to fix.
There needs to be a regression sanity test to prevent us from making this
same mistake again; but before putting that in, we'll need to get rid of
similar brain fade in the recently-added pg_replication_origin catalog.
Note: for lack of a suitable testing environment, I've not really exercised
this change. I trust the buildfarm will show up any mistakes.
This has been the predominant outcome. When the output of decrypting
with a wrong key coincidentally resembled an OpenPGP packet header,
pgcrypto could instead report "Corrupt data", "Not text data" or
"Unsupported compression algorithm". The distinct "Corrupt data"
message added no value. The latter two error messages misled when the
decrypted payload also exhibited fundamental integrity problems. Worse,
error message variance in other systems has enabled cryptologic attacks;
see RFC 4880 section "14. Security Considerations". Whether these
pgcrypto behaviors are likewise exploitable is unknown.
In passing, document that pgcrypto does not resist side-channel attacks.
Back-patch to 9.0 (all supported versions).
