Please go to the postgresql server installation directory and here you will
find one uninstall-postgresql file.

-double click on Uninstall-postgresql file to run the un-installer- it will
un-install postgresql.

II)Also you can un-install it manually.Below are the steps to un-install
postgresql 8.4 manually-

i) Remove the postgresql server installation directory. (rd /s /q
"C:\Program Files\PostgreSQL\8.4") Assuming default location.

ii) Delete the user 'postgres' (net user postgres /delete)

iii) Remove the Registry entries. (HKEY_LOCAL_MACHINE\SOFTWARE\PostgreSQL
\Installations\postgresql-8.4) and (HKEY_LOCAL_MACHINE\SOFTWARE\PostgreSQL
\Services\postgresql-8.4)

iv) Remove the postgresql-8.4 service. (sc delete postgresql-8.4)

This will completely remove your PostgreSQL 8.4 installation including user
and installation directories.
