It works, but you should use a recent version:

test=*# select count(1) over (), i from foo;count | i
-------+----    8 |  1    8 |  2    8 |  3    8 |  6    8 |  7    8 |  9    8 | 13    8 | 14
(8 rows)

test=*# select version();                                               version
--------------------------------------------------------------------------------------------------------PostgreSQL
8.4.2on x86_64-pc-linux-gnu, compiled by GCC gcc-4.3.real
 
(Debian 4.3.2-1.1) 4.3.2, 64-bit
(1 row)

test=*#
