Thank you so much, Mallah, Tomasz Myrta, Luis Sousa,
Achilleus Mantzios, Tom Lane, Bill Eaton and Oliver Elphick.

I have chmod 755 my readpgenv file, and then copied the
shell script suggested by Tomasz Myrta into that file,
yielding these results:

>biko:/usr/lib/postgresql/bin# cd /usr/bin
>biko:/usr/bin# ./psql -U postgres
>No database specified
>biko:/usr/bin# ./psql -U postgres template1
>/usr/lib/postgresql/bin/readpgenv: ./etc/postgresql/postgresql.env: No 
>such file
>  or directory

How should that file read?

>Could not execv /usr/lib/postgresql/bin/psql

Then I copied the readpgenv shell script to readpgenv.bu,
and deleted all the text from the readpgenv script,
leaving an empty file with 755 permissions.

>biko:/usr/bin# ./psql -U postgres template1
>Could not execv /usr/lib/postgresql/bin/psql

tried a different database (which exists according to pgAdmin II).

>biko:/usr/bin# ./psql -U postgres ggp_test2
>Could not execv /usr/lib/postgresql/bin/psql

Then I changed user from root to postgres,
under which this database had been created:

>biko:/usr/bin# su postgres
>biko:/usr/bin$ ./psql -U postgres ggp_test2
>Could not execv /usr/lib/postgresql/bin/psql
>biko:/usr/bin$

That's the current crop of errors following the advice to date.
As postgres, here is how my .profile in that user's home directory reads:

>biko:/usr/bin$ whoami
>postgres
>biko:/usr/bin$ cd
>biko:~$ pwd
>/var/lib/postgres
>biko:~$ ls -al
>total 20
>drwx------    3 postgres postgres     4096 Oct 15 08:42 .
>drwxr-xr-x   20 root     root         4096 Oct 14 06:43 ..
>-rw-------    1 postgres postgres     1343 Nov 16 17:45 .bash_history
>-rw-r--r--    1 postgres postgres      175 Oct 14 06:43 .profile

>PGDATA=${POSTGRES_DATA:-/var/lib/postgres/data}
>PGLIB=/usr/lib/postgresql/lib
>export PGLIB PGDATA
>biko:~$

Shouldn't these environmental variables handle what the readpgenv file is 
supposed to do for me?

Any ideas on what my next steps should be would be greatly appreciated.

Thanks,
