* Add support for PG17 (#2130)

- A new node type is introduced for JSON support, that is
  JsonConstructorExpr - wrapper over FuncExpr/Aggref/WindowFunc for
  SQL/JSON constructors.
- Added additional checks for JsonConstructorExpr expression node for
  which the walker would crash.
- Removed palloc0fast function call (which is not available in PG17)

* Update CI, README and repo settings for PG17 (#2156)

- Currently, all workflows are targeting the `PG17_prepare` branch,
  which will be changed to `PG17` once the branch is renamed.
- Updated all the github workflows
- Updated the README
- Updated repo settings
- Updated the Dockerfiles

* Remove stale bot and update .asf.yaml settings (#2171)

- Removed stale bot.
  (https://lists.apache.org/thread/qh4h2z6hsjy2v7wg8mwfnl6cbjp28y08)
- Decrease required PR approvals by one.
  (https://lists.apache.org/thread/kmz155t6k0h3b26fjpz36924zthqjlpm)
- Fixed a warning reported by apache infra i.e.
  "An error occurred while processing the github
   feature in .asf.yaml: GitHub discussions can
   only be enabled if a mailing list target exists
   for it."

* Update labeler.yml

Adjust workflow/labeler.yml to add permissions.

* Adjust CI for PG17 after rename from PG17_prepare (#2182)

Adjusted the following CI files (workflows) for PG17, they
originally pointed to PG17_prepare -

* Reimplement list comprehension (#2169) (#2188)

* Revert "Fix issue 1955 - List comprehension in WHERE clause (#2094)"

This reverts commit 0f0d9be.

* Revert "Fix error using list comprehension with WITH * (#1838)"

This reverts commit 5e08a2f.

* Revert "Fix shift/reduce conflict in grammar (#1719)"

This reverts commit fab3119.

* Revert "Implement list comprehension (#1610)"

This reverts commit 3b2b394.

* Reimplement list comprehension

- Reimplement list comprehension to use ARRAY sublinks.
- Some test results were not correct. All the test results that are
  modified are correct and are verified with neo4j.
- Also resolves the issue of using list comprehension in MERGE clause (1611)
  and issue 1850

* Add expression tree walkers for cypher nodes

- Added cypher_raw_expr_tree_walker and cypher_expr_tree_walker, based
  on Postgres's raw_expression_tree_walker and expression_tree_walker.
  These follow the same walker API as Postgres and add support for
  Cypher-specific nodes.
- Also added the agtype[] to agtype func and typecast to 1.5.0-y.y.y.sql
- Simplifies logic for cypher_subquery handling in where clause.
- Fixes a crash when list comprehension in the WHERE clause references a
  variable from the preceding MATCH clause.

* Add support for operators in cypher query (#2172)

- Fixed some operator signatures in .sql
- Added support for PG operators in cypher. Some
  hardcoded operators are removed, since they are
  now covered by the general operator handling.
- Added full typecast syntax that allows for type
  modifiers.
- These changes also improve interoperability with
  other extensions, as reflected in the regression
  tests.
- Added a new function to check if graph_oid exists.

* Prevent object access hook from accesing not installed namespace (#2161)

Currently we cannot install Age to shared_preload_libraries if
pg_cron is installed.

To prevent following error we must bail out early.
postgres=# set backtrace_functions to 'get_namespace_oid';
SET
postgres=# create extension pg_cron ;

* Fix CSV import for edge with one property (#2175)

- start_index marks where property fields begin. For edges, it's 4.
  If start_index >= total_fields, create empty properties; otherwise,
  parse the properties.
