Numeric or Integer: What's the Best PostgreSQL Datatype for Storing Currency?

What is the Best Datatype for Currency?

The Postgres Wiki recommends avoiding the Money type, except for "narrowly defined cases," as performance is its main advantage. But a more official source contradicts this claim, stating that the Money type is not officially discouraged.

When considering currency storage options in Postgres, it is important to note that decimal is simply an alias for numeric. The Postgres manual specifically recommends numeric for "storing monetary amounts and other quantities where exactness is required."

For precise currency representation, numeric offers arbitrary precision and is widely used for monetary data. However, for situations where fractional cents are not relevant, integer representing Cents provides increased efficiency.

Ultimately, the choice of datatype depends on the specific requirements of your application, considering factors such as performance and precision requirements.

How does MySQL index cardinality affect query performance? How does MySQL index cardinality affect query performance? Apr 14, 2025 am 12:18 AM

MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.
