OK it's running again many thanks ! :o)

But Tom ... could you clearly explain me what is the parameter to set in the
postgresql.conf to never have my pg_xlog partition's going full ??

I have 1.8 Gb dedicated to pg_xlog and I have set those options :
checkpoint_segments = 3 # in logfile segments, min 1, 16MB each
checkpoint_timeout = 300 # range 30-3600, in seconds
#checkpoint_warning = 30 # 0 is off, in seconds
#commit_delay = 0 # range 0-100000, in microseconds
#commit_siblings = 5 # range 1-1000

And I was only creating an index ...

I'm a little disapointed !?

regards,
