Обсуждение: size of interval type

Hi,

The document says the size of interval type is 12 bytes.

http://www.postgresql.org/docs/9.3/static/datatype-datetime.html

But ISTM the size is actually 16 bytes.
# I checked src/include/datatype/timestamp.h and pg_type system view.

Is it a document bug? Or am I missing something?

Best regards,

It's a documentation bug; the size used to be 12 bytes, but that was quite
a long time ago.  I see somebody fixed this in HEAD recently but failed to
back-patch it.
