Re: SQL Property Graph Queries (SQL/PGQ)

I have done a rough review of the patch set version 20251120.

- There are "No newline at end of file" warnings from git diff for a
couple of files:

contrib/pg_overexplain/sql/pg_overexplain.sql
src/test/regress/sql/graph_table_rls.sql

Please fix those in the next patch set, and maybe check your editor
settings.

- Attached are two small patches with some small fixes I found in
passing. (I think some of them were also reported by Junwang Zhao in
the meantime.)

- In the test files, especially src/test/regress/sql/graph_table.sql,
there are wildly different SQL styles (capitalization, formatting) used,
depending on who added the test case (I guess). Let's keep that more
consistent.

- In src/backend/parser/analyze.c, the extracted function
constructSetOpTargetlist() needs a detailed comment.

- I'm not so sure about the semantics chosen in the patch "Access
permissions on property graph". I think according to the SQL standard,
once you have access to the property graph, you don't need access to the
underlying tables as well. I guess you did this to align with how views
work? We might need to think about this a bit more, and document
whatever the conclusion is. But for now it's just small amount of code
affected.

I think you could collapse all the patches into one patch now. I have
reviewed all the incremental patches and they all look ok to me. I have
made some notes about which things I want to review in more detail, such
as the access control issue, but that doesn't need to be kept as a
separate patch.

When you create future patches, consider using the git format-patch -v
option.

And then you can also just gzip the patch. That should make it even
smaller than the .zip file.
