- Fix edge-case data corruption in shared tuplestores (Dmitry Astapov)
+ Fix edge-case data corruption in parallel hash joins (Dmitry Astapov)
- If the final chunk of a large tuple being written out to disk was
- exactly 32760 bytes, it would be corrupted due to a fencepost bug.
- This is a hazard for parallelized plans that require a tuplestore,
- such as parallel hash join. The query would typically fail later
- with corrupted-data symptoms.

- Prevent wrong tuple length
failure
- at the end of VACUUM (Ashwin Agrawal, Junfeng Yang)
-
-
-
- This occurred if VACUUM needed to update the
- current database's datfrozenxid value and
- the database has so many granted privileges that
- its datacl value has been pushed
- out-of-line.

- Prevent unsafe usage of a relation cache
- entry's rd_smgr pointer (Amul Sul)
-
-
-
- Remove various assumptions that rd_smgr
- would stay valid over a series of operations, by wrapping all uses
- of it in a function that will recompute it if needed. This prevents
- bugs occurring when an unexpected cache flush occurs partway through
- such a series.

- In pg_dump,
- avoid calling unsafe server functions before we have locks on the
- tables to be examined (Tom Lane, Gilles Darold)
-
-
-
- pg_dump uses certain server functions
- that can fail if examining a table that gets dropped concurrently.
- Avoid this type of failure by ensuring that we obtain access share
- lock before inquiring too deeply into a table's properties, and that
- we don't apply such functions to tables we don't intend to dump at
- all.
