shows how the Postgres distribution is laid out when
installed in the default way. For simplicity, we will assume that
Postgres has been installed in the directory /usr/local/pgsql
. Therefore, wherever you see the
substitute the name of the directory where Postgres is actually
installed. All Postgres commands are installed in the directory
. Therefore, you
should add this directory to your shell command path. If you use a
variant of the Berkeley C shell, such as csh or tcsh, you would add
set path = ( /usr/local/pgsql/bin path )
in the .login file in your home directory. If you use a
variant of the Bourne shell, such as sh, ksh, or bash, then you
to the .profile file in your home directory. From now on, we
will assume that you have added the Postgres bin directory to your
path. In addition, we will make frequent reference to "setting a
shell variable" or "setting an environment variable" throughout
this document. If you did not fully understand the last paragraph
on modifying your search path, you should consult the UNIX manual
pages that describe your shell before going any further.
If your site administrator has not set things up in the default
way, you may have some more work to do. For example, if the
database server machine is a remote machine, you will need to set
the PGHOST environment variable to the name of the database server
machine. The environment variable PGPORT may also have to be set.
The bottom line is this: if you try to start an application program
and it complains that it cannot connect to the postmaster, you
should immediately consult your site administrator to make sure
that your environment is properly set up.
