actually no, I changed that
set user_account www-data
ns_section ns/db/pool/pool1
ns_param maxidle 1000000000
ns_param maxopen 1000000000
ns_param connections 5
ns_param verbose $debug
ns_param extendedtableinfo true
ns_param logsqlerrors $debug
#if { $database == "oracle" } {
# ns_param driver ora8
# ns_param datasource {}
# ns_param user $db_name
# ns_param password $db_password
#} else {
ns_param driver postgres
ns_param datasource localhost::${db_name}
ns_param user $user_account
ns_param password ""
#}
pool2 and 3 are similarly adjusted
