table alias

I'm running a binary snapshot from two days ago. When I run a update with
aliases the SQL doesn't work. The alias does work if I run just a select
statement however. Is this suppose to be like this. If not is it only
broken in the 7.5 WIN32 build?

When I try an update like the one below I get the error that follows.

update report_base s
set s.sql_base = 'select * from test_data where'
where s.report_base_id = 1;

ERROR: syntax error at or near "s" at character 20

The SQL with the aliase taken out works fine as seen below.
update report_base
set sql_base = 'select * from test_data where'
where report_base_id = 1;

Query returned successfully: 1 rows affected, 282 ms execution time.

Thanks,
Bob
