PG_PASSWD !!!PG_PASSWD NAME SYNOPSIS DESCRIPTION SEE ALSO ---- !!NAME pg_passwd - change a secondary PostgreSQL password file !!SYNOPSIS __pg_passwd__ ''filename'' !!DESCRIPTION __pg_passwd__ is a tool for manipulating flat text password files. These files can control client authentication of the PostgreSQL server. More information about setting up this authentication mechanism can be found in the ''Administrator's Guide''. The format of a text password file is one entry per line; the fields of each entry are separated by colons. The first field is the user name, the second field is the encrypted password. Other fields are ignored (to allow password files to be shared between applications that use similar formats). __pg_passwd__ enables users to interactively add entries to such a file, to alter passwords of existing entries, and to encrypt such passwords. Supply the name of the password file as argument to the __pg_passwd__ command. To be used by PostgreSQL, the file needs to be located in the server's data directory, and the base name of the file needs to be specified in the ''pg_hba.conf'' access control file. $ __pg_passwd /usr/local/pgsql/data/passwords __File __y __Username: __guest __Password: Re-enter password: where the Password: and Re-enter password: prompts require the same password input which is not displayed on the terminal. Note that the password is limited to eight useful characters by restrictions of the standard crypt(3) library routine. The original password file is renamed to ''passwords.bk''. To make use of this password file, put a line like the following in ''pg_hba.conf'': host mydb 133.65.96.250 255.255.255.255 password passwords which would allow access to database mydb from host 133.65.96.250 using the passwords listed in the ''passwords'' file (and only to the users listed in that file). __Note:__ It is also useful to have entries in a password file with empty password fields. (This is different from an empty password.) Such entries allow you to restrict users who can access the system. These entries cannot be managed by __pg_passwd__, but you can edit password files manually. !!SEE ALSO ''PostgreSQL Administrator's Guide'' ----
