title: Postgresql 9.1: ERROR: type "citext" does not exist
body: <p>I am trying to execute following query through PgAdmin utility.</p>
  
  <pre><code>CREATE TABLE svcr."EventLogs" ("eventId" BIGINT NOT NULL, 
  "eventTime" TIMESTAMP WITH TIME ZONE NOT NULL, "userid" CITEXT, 
  "realmid" CITEXT NOT NULL, "onUserid" CITEXT, "description" TEXT, 
  CONSTRAINT eventlogs_pkey PRIMARY KEY ("eventId"));
  </code></pre>
  
  <p>And I get following error -</p>
  
  <pre><code>ERROR: type "citext" does not exist
  SQL state: 42704
  Character: 120
  </code></pre>
  
  <p>However, following query runs fine -</p>
  
  <pre><code>CREATE TABLE svcr."CategoryMap" ("category" INT NOT NULL, 
  "userData" INT NOT NULL);
  </code></pre>
  
  <p>What is wrong with the first query?</p>
