Hello, I have recently read about limited number of simultaneous connections on Windows when postgres is running as a service. Link is available here: http://wiki.postgresql.org/wiki/Running_%26_Installing_PostgreSQL_On_Native_Windows#I_cannot_run_with_more_than_about_125_connections_at_once.2C_despite_having_capable_hardware I tried to repeate this issue on my server ( Windows 7 32-bit, PostgreSQL 9.0.4 and max_connections set to 200) but surprisingly I was not able to do it. I used the following command: pgbench -S -c 150 -j 150 -t 2000 pgbench Does it mean that this issue does not exist anymore ?
