Introduction
	To install PostgreSQL on your Virtual Private Server, connect to your server via Telnet or SSH as root and run the following command: % vinstall pgsql The PostgreSQL installation includes all the necessary PostgreSQL files, initializes a database with the same name as your user name, and activates the postmaster daemon. Several wrapper scripts are available for all PostgreSQL commands. The wrapper scripts are automatically created when PostgreSQL is installed. PostgreSQL is installed in a version-specific directory (~/usr/local/pgsql-7.X.X) and a symlink named pgsql is created that points to that directory.
	Configuration
	If you choose to configure PostgreSQL, add the following lines to your shell startup file, according to which shell your Virtual Private Server is running. NOTE: To find out which shell your server is running, type: % echo /bin/csh - If you are using /bin/csh or one of its variants, then add the following lines to the ~/.cshrc file on your Virtual Private Server. setenv PGDATA /usr/local/pgsql/data setenv PGLIB /usr/local/pgsql/lib set path = (/usr/local/pgsql/bin ) /bin/sh & /bin/bash - If you are using the Bourne shell (/bin/sh or /bin/bash) then add the following lines to the ~/.profile file on your server: PATH=:/usr/local/pgsql/bin PGDATA=/usr/local/pgsql/data PGLIB=/usr/local/pgsql/lib export PGDATA PGLIB
	The psql Client
	The main tool for using PostgreSQL is the psql client. To start psql use this command: % psql The psql client will start up and you will be able to type in SQL code and ask for help. NOTE: You may see the following error: Connection to database '(null)' failed. FATAL: PQsetdb: Unable to determine a Postgres username! To resolve this, simply use the following command: % vpwd_mkdb ~/etc/passwd This program will read your password file at ~/etc/passwd and create a Berkeley DB format file. PostgreSQL uses this new file to look up user names and account information.
	Multi-Language Abilities in PostgreSQL
	PostgreSQL allows for a number of languages by enabling specific character-sets in the databases. When you create a database in PostgreSQL, you can use the -E flag to enable support for a specific character set. % initdb -E SET The following is a list of the available character sets and the SET name to use to enable support for it. SET   Description SQL_ASCII   ASCII EUC_JP   Japanese EUC EUC_CN   Chinese EUC EUC_KR   Korean EUC EUC_TW   Taiwanese EUC UNICODE   Unicode(UTF-8) MULE_INTERNAL   Mule Internal Code LATIN1 ISO 8859-1   English and some Europe Lang LATIN2 ISO 8859-2   English and some Europe Lang LATIN3 ISO 8859-3   English and some Europe Lang LATIN4 ISO 8859-4   English and some Europe Lang LATIN5 ISO 8859-5   English and some Europe Lang KOI8   KOI8-R(U) WIN   Windows CP1251 ALT   Windows CP866
	Removing PostgreSQL
	To remove PostgreSQL from your server, connect to it via SSH prompt, as root and do the following: % vuninstall pgsql Edit your ~/etc/rc file, removing the line that contains postmaster. Run the ps command, like this: % ps -x Determine the process ID of the PostgreSQL daemon and use kill to stop the PostgreSQL daemon: % kill PROCESS-ID
