Rationale for this change
There exists a GROUP BY usage with ALL keyword in some platforms (https://docs.snowflake.com/en/sql-reference/constructs/group-by#label-group-by-all-columns, https://duckdb.org/docs/sql/query_syntax/groupby.html).
It groups together all the columns in the SELECT statement that aren't enclosed within aggregate functions. This streamlines the syntax by keeping the list of columns in one place and helps avoid errors by ensuring that the level of detail in your SELECT matches the grouping in your GROUP BY clause.
sqlparser part supports it now with the 0.38.0 release.
What changes are included in this PR?
sqlparser is updated from 0.37.0 to 0.38.0.
select_to_plan()can handle ALL option ofGroupByExpr, by grouping all select expressions except aggregate functions..slt tests added.
Are these changes tested?
Yes, with groupby.slt tests extended.
Are there any user-facing changes?
Users can make use of GROUP BY ALL syntax for large grouping sets.
