array_cat_agg now needs to take anycompatiblearray instead of anyarray
because array_cat changed its type from anyarray to anycompatiblearray
with pg14.
To handle upgrades correctly, we drop the aggregate in
citus_pg_prepare_upgrade. To be able to drop it, we first remove the
dependency from pg_depend.
Then we create the right aggregate in citus_finish_pg_upgrade and we
also add the dependency back to pg_depend.
With pg_stat_statements queryId is calculated by default now but that
puts an extra line to explain outputs with Query Identifier. To avoid
that, we explicitly turn off this setting.

Postgres changed stats expression types as of PG14. Hence we needed to
write the AppendColumnNames method. Also they removed the error on PG
side so we remove it as well.
Relevant commits on pg14:

When queryId is not 0 and verbose is true, the query identifier is
emitted to the explain output. This is breaking Postgres outputs.
There might be a reason we process postgres tables for explain but
ideally if the explain doesn't contain any citus table, we should just
let Postgres handle it.
Commit on PG that introduced the query identifier in the explain output:

These changes were removed in commit: Introduces ExecSimpleRelationInsert_compat and modifyStateResultRelInfo macros
We shouldn't have removed them but instead kept them for before PG14
make_simple_restrictinfo and pull_varnos functions now have a new parameter
These new macros give us the ability to use this new parameter for PG14 and they don't give the parameter for previous versions

CopyFrom expects an AccessShareLock on the table. Instead of adding an
explicit lock, we do it how postgres is doing, which is to use
addRangeTableEntryForRelation.

Postgres doesn't accept NULL for queryStrings in explain plans anymore.
Internally, there are some places in Postgres where they modified the
NULLS to ""(the empty string). So we do the same on citus side.

Postgres expects to set the HASH_STRINGS explicitly in case of the
default behaivor for string hash function.

index_insert function now has a new parameter, indexUnchanged
This new macro give us the ability to use these new parameter for PG14 and they don't give the parameters for previous versions
Existing parameter is set to false

es_result_relation_info is removed from Estate. In this commit we make some changes to handle that.
resultRelationInfo filed is added to ModifyState to support the removed field.
