Yes I understand that this is "bad design" but what we are doing is storing each form field in a survey in its own column.For very long surveys we end up with thousands of elements. I know storing in an array is possible but it makes it so much easier to query the data set when each element is in its ownfield. I had lots of comments on why I should not do this and the possible alternatives and I thank everyone for theirinput but no one answered the question about compiling with a higher block size to get more columns. Can anyone answerthat? -----Original Message----- From: Tom Lane [mailto:tgl@sss.pgh.pa.us] Sent: Friday, November 12, 2010 12:24 AM To: Mark Mitchell Cc: pgsql-general@postgresql.org Subject: Re: [GENERAL] More then 1600 columns?

Generally, wanting more than a few dozen columns is a good sign that you need to rethink your schema design. What are you trying to accomplish exactly? regards, tom lane
