Are these data-types not in PG, or am I missing something?
http://www.postgresql.org/docs/current/interactive/
datatype.html#DATATYPE-NUMERIC
The docs list 2 byte, 4 byte, and 8 byte integer types.
Also, how do you calculate the size of a NUMERIC?
Lastly, I know they are the same, but which is the
"preferred/standard" type: NUMERIC or DECIMAL?
Later on, same page:
http://www.postgresql.org/docs/current/interactive/
datatype.html#DATATYPE-NUMERIC-DECIMAL
The actual storage requirement is two bytes for each group of four
decimal digits, plus eight bytes overhead.

The types decimal and numeric are equivalent. Both types are part
of the SQL standard.
The PostgreSQL are quite extensive and helpful.
