Возникли проблемы при установки drupal на СУБД POstgreSQL.
А именно:

pgsql@$ ./createdb drupal
CREATE DATABASE
pgsql@$ ./psql drupal</www/test/database/database.pgsq

большой лог, а в конце:

ERROR: language "plpgsql" does not exist
HINT: You need to use "createlang" to load the language into the database.
ERROR: language "plpgsql" does not exist
HINT: You need to use "createlang" to load the language into the database.
ERROR: function greatest(integer, integer) does not exist
HINT: No function matches the given name and argument types. You may need to add explicit type casts.

CREATE FUNCTION

После этого ничего не работает. Хотя когда делаю в psql:

drupal=# \d

Выводятся таблицы, sites/default/settings.php настроил. Видимо траблы при импорте БД database.pgsq.

P.S.: Пробовал на PostgreSQL-7.4.X, и 8.0.X
