Hi Doug.
I considered also the numeric type. In that case if the number is of 32
digits the storage size is of 2*8 + 8 = 24 bytes.
If i store it using a composite data type of two bigints the size is 2*8
+ composite data structure overhead bytes.
If the composite data type has 4 bytes overhead, I save 4 bytes for each
number... that is important because I must store many many numbers.
Performance speaking, the numeric type can be indexed?
In the case of composite data types, I must create an operator class for
indexing the fields of that type...
What is the performance gap between indexed numeric and composite?
Thank you,
Denis

Er,
What's wrong with the NUMERIC type? That can go up to hundreds of
digits.

TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match
