[firebird-support] is there a support for "create type" like postgresql ?

[ik]

Hello,

Firebird have support for "create domain" that allow me to create a
new type out from existed type.
PostgreSQL support this as well, but it also support "create type"
(http://www.postgresql.org/docs/8.3/static/rowtypes.html)
that allow to create more complex data types such as "struct" in C or
"records" in Pascal, like so:

CREATE TYPE DateDetails AS (
   ADate  Date,
   ATime Time,
   ATimeZone TimeZone,
   Epoch TIMESTAMP
);

It also seems to be supported in some-way by MS SQL-Server.
Is there any Firebird equivalent for this one ?

Thanks,
Ido
