Work Description: 11moon11 commented on pull request #10649: [BEAM-8042]
[ZetaSQL] Fix aggregate column reference
URL: https://github.com/apache/beam/pull/10649
Some aggregate operations do not require a column reference (Ex: `COUNT(*)`,
unlike `COUNT(id)`).
Such expressions should not increment reference offset when construction
`LogicalAggregate`.
