we are now going to develop a
system using PostgreSQL on Linux.
this is the first time for us to use PostgreSQL , as well as
Linux.
many things we would like to ask...
this time, the question is about SIGNALS.
I know there are some signals used for the interactions
between
postmaste
y.
or 'current' or things like this. but how can you make it
"0:00am of three days ago"?
also, if you know about it,
I'd like to know about the difference between 'current' and
'now'.
thanks about that.

DB
once in a month, so that we can save memory.
