Looks good for now, but you may consider looking at the review comments.

Note that the NOTICE, INFO, etc are just additional info to the user and are not generally considered as the "result" of the query. The result of your query is just "Success", so it would be better if you instead output some helpful information in the query result.

As an example, maybe you can take as input a set of rows containing (id, weight) in the inner query instead of (weight), and output set of (bin_number, item_id) as the result.

[krashish8]

Same as above.

Example:
INPUT: (id, weight, cost) in the inner query.
OUTPUT: (id) or maybe all three columns. I think just id is sufficient because other column values can be found out by SQL JOIN query.

I initially implemented something similar to what you are suggesting. but for the other two functions multiple knapsack and bin_packing, this approach won't make sense because each bin should have its own output table so that the user can differentiate which items are in which box

[Manas23601]

When I tried printing the output for each bin one by one, the outputs got merged into one single result query

[Manas23601]

Also Vicky Mentioned something about not wanting to user-defined types. I made some examples on that inside the sql/or_tools/plpython folder. I'll remove that in the final PR.

[Manas23601]

Is there any way to break the result query?? Same columns but different output tables.
Like

 Bin1
-------
   180
(1 row)
 BIn2
-------
   170
(1 row)

[krashish8]

Same as above.

Example:
INPUT: (id, weight, cost) in the inner query
OUTPUT: (bin_number, item_id)

For using GitHub actions, if you are facing some issues, then you can probably refer to the GitHub actions workflow used by the or-tools repository.

https://github.com/google/or-tools/blob/stable/.github/workflows/cmake_linux_python.yml#L59 or https://github.com/google/or-tools/blob/stable/.github/workflows/make_linux_python.yml#L28

I'm not building Google OR-tools from the source. I'm rather using the pip command to install it
