---------------------------------------
I have logged this {{allowQuotedId}} issue in [HIVE-23182]. Read the full
details there.
I will probably "fix" the issue here though. The "fix" I propose is to make
the default value of allowQuotedId to be 'true' instead of the current value of
'false'.

> Remove the Hive feature: REGEX Column.
>
> Hive has this interesting feature for doing REGEX to SELECT multiple columns.
> This needs to go. It is not SQL standard and as currently implemented, it
> is impossible to determine if a column identifier is a REGEX or the actual
> name of the column. If a column name is enclosed in back ticks then any
> UTF-8 character is a valid table name.
