Subject: Truncate table at a certain size.
Date: Mon, 28 Apr 2008 15:35:04 -0700
Message-ID: <1209422104.12712.12.camel@H-S12.internal.navarik.com> (raw)

Hello,

What would be the best method to truncate a table once it reaches a
certain size.   

For instance, a table named log.  I can check the size of the log;

   db=# select pg_relation_size('log');
   pg_relation_size 
   ------------------
                 8192
   (1 row)


What I would like to do is 

If table log, is greater than xxxx bytes
   then truncate table log


Maybe I'll dump it to a flat file first, (yes, it should really be a
flat file to start with, and not in a db.)

Thank you.
