PostgreSQL 8.2 Documentationto the original input. 8.1. Numeric Types Numeric types consist of two-, four-, and eight-byte integers, four- and eight-byte floating-point numbers, and selectable-precision decimals. Table 8-2 lists may not function correctly on all platforms, since it relies on compiler support for eight- byte integers. On a machine without such support, bigint acts the same as integer (but still takes up eight bytes to both sides of the decimal point. So the number 23.5141 has a precision of 6 and a scale of 4.
