Hello,

sorry for the stupid question, but why has the week number changed
from 44 to 45 this night? It is Friday, 2010-11-05 01:10, but I get now:

pref=> SELECT to_char(current_timestamp, 'YYYY-WW');
 to_char
---------
 2010-45
(1 row)

pref=> SELECT CURRENT_DATE;
    date
------------
 2010-11-05
(1 row)

pref=> SELECT CURRENT_TIME;
      timetz
-------------------
 01:12:00.65546+01
(1 row)

# date

# cat /etc/*release
CentOS release 5.5 (Final)
# rpm -qa|grep -i postgres
