Don't do that.

You could argue it either way, perhaps, but it's unlikely to get
changed. In general plpgsql cannot tell whether a variable name
appearing in a SQL command ought to be substituted for or not, and so it
just always does it. I think trying to be smart would create as many
pitfalls as it'd solve. The best practice is not to use plpgsql
variable names that match table or field names you need to access in the
same procedure.
