The file or directory can be a relative or absolute path, and can be double-quoted. Include directives only contain two fields: include, include_if_exists or include_dir directive and the file or directory to be included. The records will be inserted in place of the include directives. Include directives specify files that can be included, that contain additional records. If no record matches, access is denied.Įach record can be an include directive or an authentication record. There is no “ fall-through” or “ backup”: if one record is chosen and the authentication fails, subsequent records are not considered. ![]() The first record with a matching connection type, client address, requested database, and user name is used to perform authentication. Backslash line continuation applies even within quoted text or comments.Įach authentication record specifies a connection type, a client IP address range (if relevant for the connection type), a database name, a user name, and the authentication method to be used for connections matching these parameters. Quoting one of the keywords in a database, user, or address field (e.g., all or replication) makes the word lose its special meaning, and just match a database, user, or host with that name. Fields can contain white space if the field value is double-quoted. (Backslashes are not special except at the end of a line.) A record is made up of a number of fields which are separated by spaces and/or tabs. A record can be continued onto the next line by ending the line with a backslash. Blank lines are ignored, as is any text after the # comment character. The general format of the pg_hba.conf file is a set of records, one per line. It is possible to place the authentication configuration file elsewhere, however see the hba_file configuration parameter. ( HBA stands for host-based authentication.) A default pg_hba.conf file is installed when the data directory is initialized by initdb. > else sudo sed -i "s/127.0.0.1 localhost/127.0.0.Client authentication is controlled by a configuration file, which traditionally is named pg_hba.conf and is stored in the database cluster's data directory. This is the result of using sudo fresh out of the box.īelow, the hostname is missing in /etc/hosts, which results in the error in the command that is made to fix it, which we can then see sudo no longer results in afterwards. The install is aware of the hostname, but in my case didn't get set in /etc/hosts for localhost, sudo calls made on the system result in hostname resolution errors. I didn't see it on the issues here in a search or perusing the pages, sorry if it's a duplicate. It should be possible to add an extra command post install if detected. Fairly simple issue here, possibly an upstream bug due to the image used, as appears to be reported in a few different ubuntu images. ![]()
