Bug reference:      4815
Logged by:          Damien Guignard

PostgreSQL version: 8.3.4
Operating system:   Windows
Description:        max_connections setting has no impact
Details: 

While testing connections i tried to raise up max_connections but this
setting is never taken into account. The maximum connection (backends from
pg_stat_database) seems to be the default number : 101.

Setting in postgresql.conf :
max_connections = 200

Commands to count connections in psql CLI :
show max_connections -> 200 (ok)
but stressed whith hundreds of connections :  
select sum(numbackends) from pg_stat_database; -> 101
