Do you have two copies of postgres installed on your pc? If your distro
(what is it BTW?) has the following commands, try these (without the
quotes): "updatedb" and then "locate pgsql" to see if you have multiple
copies installed. And/or check out /usr/bin/psql. Is this a file or a
directory?

What is the home directory of postgres? Is it /home/postgres or
/usr/local/pgsql? It should be /usr/local/pgsql.

Final resort, copy your .bashrc and .bash_profile from your home
directory somewhere else for backup, remove postgres and re-install it.
Here is my *complete* install list (open to constructive comments),
(slightly) modified of course from "Practical PostgreSQL":


--------------------------------------------------------------------------------------------------------------------------------


    Installing PostgreSQL

1. Ensure that Java
<http://lanfear.syscor.priv/installs/java/index.html> and Ant
<http://lanfear.syscor.priv/installs/ant/index.html>  and readline
(ftp://ftp.gnu.org/pub/gnu/readline) are installed first and working
correctly.

2. Install the following packages:
     zliblg-dev
     libreadline4-dev
     libgcrypt-dev
     openssl
     libssl-dev
  3. Create postgres group and user (-m option creates the directory):

# groupadd postgres
# useradd -d /usr/local/pgsql -m postgres
# gpasswd -a postgres postgres

4. Download the following file into /usr/local/src, extract it as root,
and update permissions:

# cd /usr/local/src/
# tar xvzf postgresql-7.x.tar.gz
# chown -R postgres.postgres postgresql-7.x/

5. Ensure the following exists in /usr/local/pgsql/.bash_profile:

PATH=$PATH:/usr/local/java/bin:/usr/local/ant/bin:/usr/local/pgsql/bin:/usr/local/scripts
export JAVA_HOME=/usr/local/java
export ANT_HOME=/usr/local/ant

6. Configure the source tree with the following options and then compile:

# cd postgresql-7.3
# ./configure --enable-multibyte \
              --enable-odbc \
              --with-java \
              --with-maxbackends=96 \
              --with-openssl="/usr/bin/openssl" \
              --enable-syslog


# make
# cd /usr/local/src/
# chown -R postgres.postgres postgresql-7.x/


7. Regression Testing. This builds a test installation of PostgreSQL and
checks whether all parts of the source are properly compiled.

# su - postgres
$ cd /usr/local/src/postgresql-7.x
$ make check


8. Install (as root):

# cd /usr/local/postgresql-7.x
# make install
# make install-all-headers
# cd /usr/local
# chown -R postgres.postgres pgsql


9. Initialize the database as user postgres:

# su - postgres
# initdb -E UNICODE -D /usr/local/pgsql/data


10. Configure (as root) the PostgreSQL SysV Script. This script is
useful for starting, stopping, and checking the status of PostgreSQL.

# cd /usr/local/src/postgresql-7.x
# cp contrib/start-scripts/linux /etc/init.d/postgres
# chmod 755 /etc/init.d/postgres

To have PostgreSQL start automatically when the computer boots add
symbolic links from the correct /etc/rc*.d/ directories to
/etc/init.d/postgres. If the normal runlevel is 3 then you really only
need to add it to rc3.d:

# ln -s /etc/init.d/postgres /etc/rc2.d/S85postgres
# ln -s /etc/init.d/postgres /etc/rc3.d/S85postgres

etc ...

11. Start PostgreSQL for the first time:

# /etc/init.d/postgres start


12. Create a new db:

# su - postgres
$ createdb testdb
$ psql testdb


13. To shutdown:

# /etc/init.d/postgres stop


Configuration files and the server log are found in /usr/local/pgsql/data

------------------------------------------------------------------------


    Server Configuration

Edit file /usr/local/pgsql/data/pg_hba.conf:

#TYPE  DATABASE  IP_ADDRESS     NETMASK          AUTHTYPE  MAP
host   all       127.0.0.1      255.255.255.255  trust
local  all                                       trust


Edit file /usr/local/pgsql/data/postgresql.conf:

tcpip_socket = true
shared_buffers = 2048
sort_mem = 32168
syslog=1


------------------------------------------------------------------------


    System Logging

Edit the /etc/syslog.conf file to capture PostgreSQL sysloggin calls, by
adding:
local0.*            /var/log/postgresql
