CREATE TABLE oddity?

I must be missing something but I don't know what and I can't see anything in
the create table documentation (from 7.2.1) mentioning this.

When I do, in psql:

-- in this I have tried atype as int, serial and varchar
CREATE TABLE user (
something atype
);

I get the following response:

ERROR: parser: parse error at or near "user"

It is down to the table name I'm trying to use but I don't see why it's
disallowed. Is user a special reserved word in the parser?

version
---------------------------------------------------------------
PostgreSQL 7.2.3 on i686-pc-linux-gnu, compiled by GCC 2.95.2
(1 row)

psql version is the 7.2.3 install and is dynamically linked with:

libpq.so.2 => /usr/local/stow/pgsql-7.2.3/lib/libpq.so.2 (0x40014000)

Unfortunately I don't have time to investigate the source to see why I am not
allowed a table called user.

BTW, user attempting the create table is not the/a superuser and owns the
database.
