Should I migrate to postgres?

I have an application that I rewrite it (server side and client side)

The new server side will be implement in nodejs.

I consider which Database should I choose, (now it's oracle db).

My two options are PostgersSQL or stay with Oracle.

So I have some questions:

• What prefer to work with nodejs? (oracle/postgres)
• How much it take to migrate from oracle to postgres?
• Does any difference in the performance?

Thanks
