Data Types
There are four classes of data types: character, numeric, abstract and binary. Character strings can be fixed length (c and char) or variable length (text and varchar). Numeric strings can be exact numeric (i4, i2, or i1) or approximate numeric (float4 and float8). The abstract data types are date and money. Binary data can be fixed length (byte) or variable length (byte varying).
