Hi,
PostgreSQL 9.3 document in "Table 8-9" of "8.5. Date / Time Types", storage size of the interval data type has 12 bytes.
However, the definition of "datatype/timestamp.h", size of the interval data type was 16 bytes.
In addition, interval data type was 16 bytes even dump the results of the table file.
"day" field to the interval data type is added in PostgreSQL 8.1, but do not not been reflected in the document PostgreSQL at that time?
Regards.
