title: Create table never ending
body: <p>I try to create table in my Postgres database. I use pgadmin in version 1.18.1. Postgres version on server is 8.3.12.</p>
  
  <p>When I execute create table statement, usually it done in few ms, but sometimes it go on few minutes and I stopping it. Then I have to restart the Postgres server, which is undesirable. I tried create table before people come to work, but that didn't work too.</p>
  
  <p>Has someone similar problem? How can I fix that?
  Restart server is sometimes really problematic.</p>
