David,
No, it's not now an array.
I thought that this expression would work, but it doesn't:
bustrac=# alter table people alter column email set data type varchar(64)[] using email::varchar(64)[];
RROR: malformed array literal: "frank@dmipx.com"
DETAIL: Array value must start with "{" or dimension information.
If I correctly understand the error detail I'd need to change the contents
of that column for all 1280 rows to enclose the contents in curly braces
before I can convert the datatype to an array. Is that correct?
