How to configure windows postgresql pg_hba.conf?

Client authentication is controlled by a configuration file, which traditionally is pg_hba.conf and is store in the database cluster’s data directory.

A default pg_hba.conf file is install when the data directory is initialized by initdb.

It is possible to place the authentication configuration file elsewhere, however; see the hba_file configuration parameter.

The general format of the pg_hba.conf file is a set of records, one per line.

Blank lines are ignored, as is any text after the # comment character.

A record can continue onto the next line by ending the line with a backslash.

A record is made up of a number of fields which are separate by spaces and/or tabs.

Fields can contain white space if the field value is double-quote.

Quoting one of the keywords in a database, user, or address field makes the word lose its special meaning, and just match a database, user, or host with that name.

Backslash line continuation applies even within quoted text or comments.

Each record specifies a connection type, a client IP address range, a database name, a user name, and the authentication method to use for connections matching these parameters.

The first record with a matching connection type, client address, request database, and user name is use to perform authentication.

There is no “fall-through” or “backup”: if one record is chosen and the authentication fails, subsequent records are not consider.

If no record matches, access is deny.

Today, let us see the steps followed by our support techs to configure windows postgresql pg_hba.conf

Installing and configuring PostgreSQL

Firstly, download and install PostgreSQL.Visit https://www.enterprisedb.com/downloads/postgres-postgresql-downloads to see a list of support operating systems and download the installer.
Then, open the postgresql.conf configuration file. This file is locate at %postgresql_dir%\data. Here %postgresql_dir% is the folder that PostgreSQL was install in.
Next, specify the IP address that Kaspersky Scan Engine must use to connect to PostgreSQL in the listen_addresses setting of postgresql.conf.
Then, specify the port on which the PostgreSQL is to listen for connections from Kaspersky Scan Engine in the port setting of postgresql.conf.
Next, save and close postgresql.conf.
Next, open the pg_hba.conf configuration file. This file is locate in the same folder as postgresql.conf.
Then, make sure that PostgreSQL requires an MD5-encrypt password for authentication from all of its clients. Find the following line in pg_hba.conf:host all all 127.0.0.1/32 md5If the authentication method specify on this line is other than md5, change it to md5.
If PostgreSQL and Kaspersky Scan Engine are install on different computers, add the following line to pg_hba.conf:host all all %IP%/32 md5Here %IP% is the IP address of the computer on which Kaspersky Scan Engine is install.
Then, save and close pg_hba.conf.
Finally, restart PostgreSQL by running the following command from the command line:sc stop postgresql-x64-11sc start postgresql-x64-11
