sequence/serial types - Mailing list pgsql-novice

I downloaded and installed the PostgreSQL 6.0 binaries for Solaris x86.  the
installation went fine, as did the subsequent database and table creations.
however, psql complains when i try to use CREATE SEQUENCE or SERIAL.  does
6.0 support SEQUENCE types?  which version was it introduced?  i would like
to use a later version of Postgres, but last time i tried to build the
latest version on my box (SunOS brooklyn 5.8 Generic i86pc i386 i86pc) it
wouldn't build.

Thanks in advance,

Sal
