Why smallint is mapped to int32 by default?

"smallint": func(string) string { return "int32" },

I searched in Postgres docs and MySQL docs and found out that both of their smallint types hava a storage size of 2 bytes. So I'm wondering why smallint is currently mapped to int32 by default. Will int16 be a better choice?

The default type is determined based on business usage; generally, int16 is rarely used, and more int32 is used.
If it does not meet your needs, you can configure it through Data Mapping.
