Multiple database connection in single connection pool using Node JS - node.js

Question

I am trying to create a database connection pool in Node js using generic-pool package. With single database the pool is working fine but I want to use more than one database in single pool to be use. In this context I am facing issue. Generic pool is not creating pool for both the database in single pool. Below is my code. I am using trireme-jdbc for JDBC connection ang generic-pool for connection pooling.
var Pool = require('C:JCI/trireme-jdbc/node_modules/generic-pool').Pool;
var jdbc = require('C:/Program Files/nodejs/node_modules/trireme-jdbc');
var configOpenedge = require('C:/Program Files/nodejs/node_modules/trireme-jdbc/testconf/config-openedge.js');
var configPostgre = require('C:/Program Files/nodejs/node_modules/trireme-jdbc/testconf/config-postgre.js');
var pool = new Pool({
name : 'Anil-JCI',
create : function(callback) {
var connOpenedge = new jdbc.Database({
url : configOpenedge.url,
properties : configOpenedge.properties,
});
var connPostgre = new jdbc.Database({
url : configPostgre.url,
properties : configPostgre.properties,
/*
* minConnections : 1, maxConnections : 2000, idleTimeout : 60
*/
});
callback(null, connOpenedge);
},
destroy : function(client) {
client.end();
},
max : 10,
// optional. if you set this, make sure to drain() (see step 3)
min : 2,
// specifies how long a resource can stay idle in pool before being removed
idleTimeoutMillis : 30,
// if true, logs via console.log - can also be a function
log : true
});
console.log("connection created");
pool.acquire(function(err, clientOpenedge, clientPostgre) {
if (err) {
throw err;
}
else {
clientOpenedge.execute(
'select * from "po" where "po-num" = ? and "vend-num" = ? ', [
4322452, 4301170 ], function(err, result, rows) {
// pool.release(client);
console.log(err);
rows.forEach(function(row) {
console.log(row);
});
console.log("Openedge Data Printed...");
});
clientPostgre.execute("select * from employees ",
[ ], function(err, result) {
// pool.release(client);
console.log("we are in postgre");
console.log(result);
console.log("Postgre Data Printed...");
});
}
});
