 ### The user groups a 'Money' data type column
+
 The user might also choose to group the data based on the values of the 'Money' data type column.
 
 # Review Notes
+
 - For the MVP we'll assume the number locale format based on the selected currency. Eventually we can add options so that, for example, US dollars can be displayed with dot separators instead of commas. 
-- All locales will be included whenever there's a locale related option.

+## Update 23 Feb 2022
+
+### Compatibility with Postgres Money Type
+
+Mathesar will allow users to view columns set to Postgres money type as a money type column. However, it will not allow users to set an existing column to Postgres money data type. To change from Postgres money data type to the custom Mathesar money type, the user would have to set the column to Number or other data type and then choose money again.

+
+### Support for Multi-Currency through custom Mathesar Money Type
+
+Mathesar's custom money data type will allow users to set any currency and customize various display options. The custom money data type will be the only money type option that can be set in Mathesar. With Postgres money type being available only for existing database columns set to this type.

 We want to make sure users of all levels can understand and use the appropriate data types. Because the distinction between database types is sometimes not evident to beginner levels, we want to map them to more familiar categorizations. The design ensures that information will be available but prioritizes the user-friendly types in terms of visibility.
