pg_hba.conf(5)

NAME
$PGDATA/pg_hba.conf

DESCRIPTION
"Host-based access control" is the name for the basic controls Postgres exercises on what clients are allowed to access a database system. It is called that because one of the factors that can control access is from what host the client is connecting.

Each database system contains a file named "pg_hba.conf", in its PGDATA directory, that controls who can connect to that database system.

The exact format of the pg_hba.conf file is described in the comments at the top of the sample file pg_hba.conf.sample, which resides in the Postgres "library" directory.
