+# PostgreSQL Client Authentication Configuration File
+# ===================================================
+#
+# Refer to the "Client Authentication" section in the PostgreSQL
+# documentation for a complete description of this file.  A short
+# synopsis follows.
+#
+# This file controls: which hosts are allowed to connect, how clients
+# are authenticated, which PostgreSQL user names they can use, which
+# databases they can access.  Records take one of these forms:
+#
+# local         DATABASE  USER  METHOD  [OPTIONS]
+# host          DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
+# hostssl       DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
+# hostnossl     DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
+# hostgssenc    DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
+# hostnogssenc  DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
+#
+# (The uppercase items must be replaced by actual values.)
+#
+# The first field is the connection type:
+# - "local" is a Unix-domain socket
+# - "host" is a TCP/IP socket (encrypted or not)
+# - "hostssl" is a TCP/IP socket that is SSL-encrypted
+# - "hostnossl" is a TCP/IP socket that is not SSL-encrypted
+# - "hostgssenc" is a TCP/IP socket that is GSSAPI-encrypted
+# - "hostnogssenc" is a TCP/IP socket that is not GSSAPI-encrypted
+#
+# DATABASE can be "all", "sameuser", "samerole", "replication", a
+# database name, or a comma-separated list thereof. The "all"
+# keyword does not match "replication". Access to replication
+# must be enabled in a separate record (see example below).
+#
+# USER can be "all", a user name, a group name prefixed with "+", or a
+# comma-separated list thereof.  In both the DATABASE and USER fields
+# you can also write a file name prefixed with "@" to include names
+# from a separate file.
+#
+# ADDRESS specifies the set of hosts the record matches.  It can be a
+# host name, or it is made up of an IP address and a CIDR mask that is
+# an integer (between 0 and 32 (IPv4) or 128 (IPv6) inclusive) that
+# specifies the number of significant bits in the mask.  A host name
+# that starts with a dot (.) matches a suffix of the actual host name.
+# Alternatively, you can write an IP address and netmask in separate
+# columns to specify the set of hosts.  Instead of a CIDR-address, you
+# can write "samehost" to match any of the server's own IP addresses,
+# or "samenet" to match any address in any subnet that the server is
+# directly connected to.
+#
+# METHOD can be "trust", "reject", "md5", "password", "scram-sha-256",
+# "gss", "sspi", "ident", "peer", "pam", "ldap", "radius" or "cert".
+# Note that "password" sends passwords in clear text; "md5" or
+# "scram-sha-256" are preferred since they send encrypted passwords.
+#
+# OPTIONS are a set of options for the authentication in the format
+# NAME=VALUE.  The available options depend on the different
+# authentication methods -- refer to the "Client Authentication"
+# section in the documentation for a list of which options are
+# available for which authentication methods.
+#
+# Database and user names containing spaces, commas, quotes and other
+# special characters must be quoted.  Quoting one of the keywords
+# "all", "sameuser", "samerole" or "replication" makes the name lose
+# its special character, and just match a database or username with
+# that name.
+#
+# This file is read on server startup and when the server receives a
+# SIGHUP signal.  If you edit the file on a running system, you have to
+# SIGHUP the server for the changes to take effect, run "pg_ctl reload",
+# or execute "SELECT pg_reload_conf()".
+#
+# Put your actual configuration here
+# ----------------------------------
+#
+# If you want to allow non-local connections, you need to add more
+# "host" records.  In that case you will also need to make PostgreSQL
+# listen on a non-local interface via the listen_addresses
+# configuration parameter, or via the -i or -h command line switches.
+
+# CAUTION: Configuring the system for local "trust" authentication
+# allows any local user to connect as any PostgreSQL user, including
+# the database superuser.  If you do not trust all your local users,
+# use another authentication method.
+
+
+# TYPE  DATABASE        USER            ADDRESS                 METHOD
+
+# "local" is for Unix domain socket connections only
+local   all             all                                     trust
+# IPv4 local connections:
+host    all             all             0.0.0.0/0               trust

+## Vlang ZDB Client
+
+to use:

+- build zero db from source: https://github.com/threefoldtech/0-db
+- run zero db from root of 0db folder:
+  `./zdbd/zdb --help || true` for more info
+
+## to use test
+
+```bash
+#must set unix domain with --socket argument when running zdb
+#run zdb as following:  
+mkdir -p ~/.zdb
+zdb --socket ~/.zdb/socket --admin 1234
+redis-cli -s ~/.zdb/socket
+#or easier:
+redis-cli -s ~/.zdb/socket --raw nsinfo default
+```
+
+then in the redis-cli can do e.g.
+
+```
+nsinfo default
+```
