<div dir="ltr">CREATE MATERIALIZED VIEW statement ends up being CREATE TABLE AS statement underneath with table type
matview.In that case, why don't I see special treatment only for materialized view and not CTAS in general, which
allowscolumn names to specified like the case in the bug reported.<br /></div><div class="gmail_extra"><br /><br /><div

thediscussion to the -hackers list to discuss the fix.<br /><br /> This bug was introduced in
fb60e7296c2cf15195802b4596496b179bdc905a<br/> based on this feedback:<br /><br /><a

target="_blank">http://www.postgresql.org/message-id/20600.1363022702@sss.pgh.pa.us</a><br/><br /> I picked the wrong
responseto that feedback. Attached is a patch<br /> which fixes things along the alternative lines suggested. This<br
/>includes a regression test to ensure that this doesn't get broken<br /> again.<br /><br /> If there are no objections
I'llapply this within a few days.<br /><br /> --<br /> Kevin Grittner<br /> EDB: <a href="http://www.enterprisedb.com"
