Re: table is hanging

    To find out if there is some locking problem or just takes time
      for the client to handle the data, ask just for a small subset of
      the table.
    

    If 

    
    select * from table limit 1; 

    
    works it is probably just taking a lot of time to send all the
      data to the client.
    If the data set includes something large also 1 ow can be heavy.
    You can even try with limit 0 to just find out if the table
      responses.
    The client software is often the largest bottleneck, not the
      database.
