Hello all

When configuring mediawiki (1.11.2 ) using postgresql 8.3 I get the following failure message:

# Database type: PostgreSQL
# Loading class: DatabasePostgres
# Attempting to connect to database "postgres" as superuser "postgres"...
# Checking the version of Postgres...version 8.3 is OK.
# User "wikiuser" already exists, skipping account creation.
# Database "wikidb" already exists, skipping database creation.
# Connecting to "wikidb" as superuser "postgres" to check rights...OK
# Checking that tsearch2 is installed in the database "wikidb"...FAILED. tsearch2 must be installed in the database "wikidb".Please see this article for instructions or ask on #postgresql on irc.freenode.net

tsearch2 shouldnt need to be installed as its included in the core of postgresql 8.3 so what am i missing, doing wrong??? I see that there is a trigger called tsearch2 in the wikidb....

Thanks in advance!
