What is a key consideration when converting Oracle's BOOLEAN data type to PostgreSQL?

Using VARCHAR with 'true' and 'false'

Using INTEGER with 0 and 1

Using CHAR(1) with 'T' and 'F'

Using BOOLEAN directly

None

PostgreSQL supports the BOOLEAN data type natively, which can be used directly for Oracle's BOOLEAN values.

What is a common pitfall when converting Oracle's DATE data type to PostgreSQL?

Assuming DATE includes time

Using TIME data type

Using TIMESTAMP instead of DATE

Ignoring time zone differences

None

In Oracle, the DATE data type includes both date and time, whereas in PostgreSQL, DATE only includes the date. This can lead to data loss if not handled properly.
