Release 2.5.0

Browse Source 
This release adds major new features since the 2.4.2 release.
We deem it moderate priority for upgrading.

This release includes these noteworthy features:

* Continuous Aggregates for Distributed Hypertables
* Support for PostgreSQL 14
* Experimental: Support for timezones in `time_bucket_ng()`, including
the `origin` argument

This release also includes several bug fixes.

**Features**
* #3034 Add support for PostgreSQL 14
* #3435 Add continuous aggregates for distributed hypertables
* #3505 Add support for timezones in `time_bucket_ng()`

**Bugfixes**
* #3580 Fix memory context bug executing TRUNCATE
* #3592 Allow alter column type on distributed hypertable
* #3598 Improve evaluation of stable functions such as now() on access
node
* #3618 Fix execution of refresh_caggs from user actions
* #3625 Add shared dependencies when creating chunk
* #3626 Fix memory context bug executing TRUNCATE
* #3627 Schema qualify UDTs in multi-node
* #3638 Allow owner change of a data node
* #3654 Fix index attnum mapping in reorder_chunk
* #3661 Fix SkipScan path generation with constant DISTINCT column
* #3667 Fix compress_policy for multi txn handling
* #3673 Fix distributed hypertable DROP within a procedure
* #3701 Allow anyone to use size utilities on distributed hypertables
* #3708 Fix crash in get_aggsplit
* #3709 Fix ordered append pathkey check
* #3712 Fix GRANT/REVOKE ALL IN SCHEMA handling
* #3717 Support transparent decompression on individual chunks
* #3724 Fix inserts into compressed chunks on hypertables with caggs
* #3727 Fix DirectFunctionCall crash in distributed_exec
* #3728 Fix SkipScan with varchar column
* #3733 Fix ANALYZE crash with custom statistics for custom types
* #3747 Always reset expr context in DecompressChunk

**Thanks**
* @binakot and @sebvett for reporting an issue with DISTINCT queries
* @hardikm10, @DavidPavlicek and @pafiti for reporting bugs on TRUNCATE
* @mjf for reporting an issue with ordered append and JOINs
* @phemmer for reporting the issues on multinode with aggregate queries and evaluation of now()
* @abolognino for reporting an issue with INSERTs into compressed hypertables that have cagg
* @tanglebones for reporting the ANALYZE crash with custom types on multinode
