Systems view which gives creation date for a table?

Hi all,

    I would like to be able to query some systems table or view to 
obtain the creation data of a table.  INFORMATION_SCHEMA does not seem 
to record this information.  Does postgres store it somewhere?

    I need this for a PHP/postgres application which creates temporary 
tables which should be cleaned up when my application finishes.  But 
sometimes they aren't., so I have to write code to find these tables and 
drop them.  There is a better solution -- to use CREATE TEMPORARY 
TABLE.  But to do this I would have to use PHP persistent data base 
connections which, unlike the ordinary connections which my application 
currently uses, drop and recreate connections when I move from one page 
to another. 
Changing means a significant code rewrite.  I could, of course, encode 
the creation date into the name of the table.

   But I would like to know how to find the creation date of a table.

   Thanks in advance

Mary Anderson
