Christophe,

I'm not using the proper syntax and the postgres alter table doc has no
example in the alter column choices.

What I've tried:
bustrac=# alter table people alter column email set data type varchar(64) [];
ERROR:  column "email" cannot be cast automatically to type character varying[]
HINT:  You might need to specify "USING email::character varying(64)[]".

How do I incorporate the "USING email::..." string?

TIA,

Rich
