Well, I looked through the patch and didn't find any issues, so I'll
mark this ready for committer.
Last implementation differs from the original one and is based on
suggestion from this message:
https://www.postgresql.org/message-id/2906.1542395026%40sss.pgh.pa.us
It does eval_const_expressions() earlier and pulls up only Const functions.
I also added a few more tests and comments.
New version is in attachments.
