- Fix incorrect compression logic for GIN posting lists
- (Heikki Linnakangas)
-
-
-
- A GIN posting list item can require 7 bytes if the distance between

- of sync with that, and might try to write the value into a 6-byte
- buffer. In principle this could cause a stack overrun, but on most
- architectures it's likely that the next byte would be unused
- alignment padding, making the bug harmless. In any case the bug
- would be very difficult to hit.

- In psql, resynchronize internal state

-

-
- Ordinarily this is unnecessary since the state would be the same
- anyway. But it can matter in corner cases, such as where the
- connection might lead to one of several servers. This change
- causes psql to re-issue any interactive
- messages that it would have issued at startup, for example about

- Fix pg_dump's handling of circular
- dependencies in views (Tom Lane)
-
-
-
- In some cases a view may depend on an object
- that pg_dump needs to dump later than the
- view; the most common example is that a query using GROUP
- BY on a primary-key column may be semantically invalid
- without the primary key. This is now handled by emitting a
- dummy CREATE VIEW command that just establishes
- the view's column names and types, and then later
- emitting CREATE OR REPLACE VIEW with the full
- view definition. Previously, the dummy definition was actually
- a CREATE TABLE command, and this was
- automagically converted to a view by a later CREATE
- RULE command. The new approach has been used successfully
- in PostgreSQL version 10 and later. We
- are back-patching it into older releases now because of reports that
- the previous method causes bogus error messages about the view's
- replica identity status. This change also avoids problems when
- trying to use the option during a restore
- involving such a view.

- Fix contrib/intarray's GiST opclasses to not

-
-
-
- A clause like array_column
- <@ constant_array is
- considered indexable, but the index search may not find index
- entries for empty arrays in the array column; of course, such
- entries should trivially match the search.
-
-
-
- The only practical back-patchable fix for this requires
- making <@ index searches scan the whole index,
- which is what this patch does. This is unfortunate: it means that
- the query performance is likely worse than a plain sequential scan
- would be.
-
-
-
- Applications whose performance is adversely impacted by this change
- have a couple of options. They could switch to a GIN index, which
- doesn't have this bug, or they could replace
- array_column
- <@ constant_array
- with array_column
- <@ constant_array
- AND array_column
- && constant_array.
- That will provide about the same performance as before, and it will
- find all non-empty subsets of the given constant array, which is all
- that could reliably be expected of the query before.
