Unless otherwise noted, the commands and paths noted in the following section assume that you have performed an installation with the interactive installer.You can easily update parameters that determine the behavior of Advanced Server and supporting components by modifying the following configuration files:
• The postgresql.conf file determines the initial values of Advanced Server configuration parameters.
• The pg_hba.conf file specifies your preferences for network authentication and authorization.
• The pg_ident.conf file maps operating system identities (user names) to Advanced Server identities (roles) when using ident-based authentication.You can use your editor of choice to open a configuration file, or navigate through a menu to open the file:
• To update configuration files in Linux, navigate through the EDB Postgres menu selection on the Applications menu to the Advanced Server 10 menu; use the Expert Configuration menu to select the configuration file that you would like to edit (see Figure 6.1).
