      • resolveType

        PGAnyType resolveType​(java.lang.String name)
               throws java.sql.SQLException
        Resolves a name to an SQLType suitable for passing to any method that accepts one. As the method queries the server for the type information any type name acceptable to the server is allowed (i.e. qualified, unqualified, quoted, etc.) Using this method allows the resolution of a name to a type to be re-used; speeding up performance in cases where named types are used. NOTE: The possibility of DDL changing the name to type mapping means named types are always looked up when used. This ensures that the correct type is used always. When resolving a named type using this method it is only valid as long as no commands are issued that invalidate it (e.g. dropping and re-adding a type or extension).
        Parameters:
        name - Name of type to resolve (anything acceptable to the server)
        Returns:
        Type instance representing the current name to type mapping.
        Throws:
        java.sql.SQLException
