Method Name

postgres/parser/types/types.go:1297–1375

Name returns a single word description of the type that describes it succinctly, but without all the details, such as width, locale, etc. The name is sometimes the same as the name returned by SQLStandardName, but is more CRDB friendly. TODO(andyk): Should these be changed to be the same as SQLStan
