SQL syntax rowcount value as an extra column in the result set

Hello

I'm using PostgreSQL (8.4.701) and Java (jdbc,
postgresql-8.4-701.jdbc4.jar) to connect to the database.

My question is: what is the SQL syntax for PostgreSQL to achieve the
following:

I want to receive the rowcount along with the rest of a result set. For
example, let's say the following query returns

select first_name from people;

first_name
=========
Mary
Sue
Joe

and the following query returns the value

select count(*)as ROWCOUNT from people;
ROWCOUNT
==========
3
3

What I'm looking for is the output as

ROWCOUNT , first_name
=====================
3 , Mary
3 , Sue
3 , Joe

so I can use JDBC (snip-it) as follows:

resultSet.getInt("ROWCOUNT")
resultSet.getString("first_name")

On a side note, Oracle allows the following syntax to achieve the above:

select count(*) over () as ROWCOUNT , first_name from people

Thanks,Jim
