Master to PostgreSQL version 16 (#1451)

* Initial PG16 version (#1237)

Fixed empty string handling.

Previously, the PG 16 outToken emitted NULL for an empty string, but now it emits an empty string "". Consequently, our cypher read function required modification to properly decode the empty string as a plain token, thereby addressing the comparison issue.

Compared the branches and added the necessary changes so that the query's rteperminfos variable doesn't stay NULL.

Fix missing include varatt.h (causing undefined symbol VARDATA_ANY) & Fixing some test cases of the failings

Added missing include varatt.h to fix the undefined symbol while loading age into postgresql because usage of VARDATA_ANY needs to import varatt.h in PG16

Modified initialisation of ResultRelInfo and removed unnecessary RTEs

Compared the branches and added the necessary changes so that the query's rteperminfos variable doesn't stay NULL.

Modified initialisation of ResultRelInfo and removed unnecessary RTEs

One of the problems that we were facing was related to the ResultRelInfo pointing at the wrong RTE via its ri_RangeTableIndex. The create_entity_result_rel_info() function does not have the capability of setting the ri_RootResultRelInfo to the correct ResultRelInfo node because it does not have access to the ModifyTableState node. The solution for this was to set the third argument in InitResultRelInfo() to be zero instead of list_length(estate->es_range_table).

In the update_entity_tuple() function, when we call table_tuple_update() and assign the returned value to the result variable, the buffer variable receives the value of 0.
Made a workaround so that the original value isn't lost.

This is a work in progress for the new field that was added to the struct Var called varnullingrels. According to the documentation, this field is responsible for marking the Vars as nullable, if they are coming from a JOIN, either LEFT JOIN, RIGHT JOIN, or FULL OUTER JOIN. The changes were made following an "optional match" clause which is being treated as a LEFT JOIN from our extension.

A function markRelsAsNulledBy is added because its internal in Postgres and doesn't belong in a header file, therefore it can't be exported. This function is added before the creation of the Vars from the make_vertex_expr and make_edge_expr, to correctly mark the specific PNSI as nullable, so later in the planner stage, the Vars will be correctly nulled.

Fix incorrect typecasting in agtype_to_graphid function.

Fix incorrect returns to the fuction _label_name, _ag_build_vertex and _ag_build_edge.

* Fix Docker files to reflect PostgreSQL version 16 (#1448)

Fixed the following Docker files to reflect running under
PostgreSQL version 16.

    modified:   docker/Dockerfile
    modified:   docker/Dockerfile.dev

This impacts the DockerHub builds.

* Mark null-returning RTEs in outer joins as nullable

RTEs that appear in the right side of a left join are marked as 'nullable'.
The column references to a nullable RTE within the join's RTE are also
marked as 'nullable'. This concept is introduced in Postgresql v16.

The change in Postgresql v16's pullup_replace_vars_callback() function causes
different plans to be generated depending on whether appropriate RTEs are
marked nullable. Without marking nullable, in a left join, any function call
expression containing right RTE's columns as arguments are not evaluated at
the scan level, rather it is evaluated after the join is performed. At that
point, the function call may receive null input, which was unexpected in
previous Postgresql versions.

See:

  - Postgresql v16's commit: Make Vars be outer-join-aware
    https://www.postgresql.org/message-id/[email protected]

  - The 'Vars and PlaceHolderVars' section in the Postgresql v16's
    optimizer/README.md

* Fix minor code formatting.
