Really weird...
Anyway, what you could do first it's to rename the 8.3.2 command to
disable it. Locate "psql" command of your PostgreSQL version 8.3.2, ex.
/usr/bin. Inside the directory, type "sudo mv -i psql psql-8.3.2". Now,
type "psql --version". If the command is found and the version is
changed to 9.2.4, your lucky. If a "command not found" message appears,
you have to add the path of your new version of PostgreSQL commands to
your PATH variable. Here below the process...
To edit PATH variable for your whole Ubuntu system, type "sudo gedit
/etc/environment" (gedit or your favorite editor). A line like
«PATH="....."» should appear. Add your 9.2.4 command path to the
variable. Save the file, close your terminal and reopen it and it should
work. Be carefull in your editing. You could scrap your PATH variable
and lose all your Linux commands. You should make a copy of this file in
your /home directory before editing it. If you scrap it, you could type
the full path of your Linux command, e.g. "sudo /usr/bin/gedit
/etc/environment" to correct the problem or reinstall the backup file.
If the path of your 8.3.2 version is NOT a general path like "/usr/bin"
or "/usr/local/bin", you could remove it from your PATH environment
variable to disable all old PostgreSQL commands. But if it is, you must
rename all the old PostgreSQL command to disable them, ex. pg_dump,
pg_restore, etc.
After those operations, you must type the full path to access old 8.3.2
PostgreSQL commands and type only the command without full path to
access new 9.2.4 PostgreSQL commands.
Hope it will be usefull
