how to get a table's age - Mailing list pgsql-general

Howdy:

Running PostgreSQL 7.2.1 on RedHat Linux 7.2.

Is there a way to get a tables age from within the
database? 

What I mean is, I know that I have created a list of temporary
tables, but I may not know what they are.  I would like to
create a script that drops those tables by a date parameter
(if the age of t_table is > 60 days; drop t_table) rather than
dropping the tables by name association (t_table).

Suggestions?  Comments? 

Thanks!
