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)[]".
What I forgot to mention is that the current datatype is varchar(64) and I
want to make it an array.
Yeah, the simply cast suggested will not work. You’d have to apply an expression that turns the current contents into an array. The current contents are not likely to be an array literal.
