You can `GROUP BY` expressions, column names (`:col1`), or table and column (`:table.col1`),
or aliases (`:some.alias`). Since there is ambiguity between the formatting
of those, you can use the special syntax `[:alias :some.thing]` to tell
HoneySQL to treat `:some.thing` as an alias instead of a table/column name.
## having
The `:having` clause works identically to `:where` above
