Available Public Wildcard DNS Domains pointing to localhost (127.0.0.1)

It turns out that some kind hearted people already set up wildcard domains for you already. You can use any domain below and/or any subdomain of these and they currently resolve to 127.0.0.1 but could switch at any time to resolve somewhere else. Here's the list of ones I know about. Let me know if there are more!

• localhost - It will always works. Do you know why? I hope so.
• [*.]fuf.me - Managed by @fidian; it will always point to localhost for IPv4 and IPv6
• [*.]fbi.com - 👏 👏 👏 👏 👏
• [*.]localtest.me
• [*.]127-0-0-1.org.uk
• [*.]vcap.me

First of all, please note that token expiration and revoking are two different things.

1. Expiration only happens for web apps, not for native mobile apps, because native apps never expire.
2. Revoking only happens when (1) uses click the logout button on the website or native Apps;(2) users reset their passwords; (3) users revoke their tokens explicitly in the administration panel.

1. How to hadle JWT expiration

A JWT token that never expires is dangerous if the token is stolen then someone can always access the user's data.

Quoted from JWT RFC:

psql: FATAL: Peer authentication failed for user “postgres” (or any user)

The connection failed because by default psql connects over UNIX sockets using peer authentication, that requires the current UNIX user to have the same user name as psql. So you will have to create the UNIX user postgres and then login as postgres or use sudo -u postgres psql database-name for accessing the database (and psql should not ask for a password).

If you cannot or do not want to create the UNIX user, like if you just want to connect to your database for ad hoc queries, forcing a socket connection using psql --host=localhost --dbname=database-name --username=postgres (as pointed out by @meyerson answer) will solve your immediate problem.

But if you intend to force password authentication over Unix sockets instead of the peer method, try changing the following pg_hba.conf* line:
