Hi All,
I am trying to alter column from "timestamp without timezone" to
"bigint" but getting below error:
#ALTER TABLE test ALTER column time type bigint;
#ERROR: column "time" cannot be cast to type bigint
Is there any other method for alter column to bigint.
This should do it:
ALTER TABLE test ALTER column time type bigint USING extract(epoch from time)
(Btw: I would avoid column names that are keywords like "time")
