From the point of view of the user, VALUES cannot be empty.

[chenjian2664]

@kasiafi PTAL

[kasiafi]

From the point of view of the user, VALUES cannot be empty.

True. How about "Fix planning failure of certain queries where part of the plan is optimized to empty values."?

[ebyhr]

@chenjian2664 Could you sort entries by the following rule?

@wendigo @martint I am not add RN for #27341, could you confirm that #27341 (comment) by @findepi

[chenjian2664]

cc @Praveen2112 @wendigo Please help to advice

[findepi]

Is this for internal communication only?

[chenjian2664]

cc @ksobolew

[ksobolew]

Yes, this is internal communication

[findepi]

SET DEFAULT is not a statement
ALTER TABLE .. ALTER COLUMN .. SET DEFAULT is.

not sure how to phrase it, but it needs a change for sure.

[chenjian2664]

same.
updated to "Add support for setting and dropping column defaults via ALTER TABLE ... ALTER COLUMN" at current.

[findepi]

This does not convey what's the end user visible change.
Also link might is wrong. Is this #26349? There is another bullet below also linking to #21506, related to #27191 PR.

[chenjian2664]

It's linking to 21506 because it fixes it. should we put also pr number here as well?

the release notes should be: Fix query failure when UNION involve empty values branch ? @kasiafi @Max-Cheng

[findepi]

Fix server startup failure when partitioned spooling is configured.
This is spooling-filesystem plugin change. Still in General section?

squashed commits & fix format

[raunaqmorarka]

It automatically falls back to the old scalar implementation
