   Just thought you'd like another data point.  I just installed Cristian's
   glibc2-2.0.7 packages.  Like Thomas, I still get:
   
   	postgres=> select '1 min'::timespan;
   	?column?    
   	------------
   	@ 60.00 secs
   	(1 row)
   
   Without recompiling.  With recompiling, I get:
   
   	postgres=> select '1 min'::timespan;
   	?column?
   	--------
   	@ 1 min 
   	(1 row)
   
   
   I'm using gcc 2.7.2.3 -O2.

   Well, this narrows it down a lot! Wonder why it requires a recompile?? afaik there
   isn't any static library linking involved...

   Maybe you were using my postgresql package which was a little older ?
   
   I have new rpms on ftp://ftp.redhat.com/home/gafton/pgsql
