Re: [SQL] please help me on regular expression

Some people, when confronted with a problem, think "I know, I'll use
regular expressions." Now they have two problems. — Jamie Zawinski

[SQL] internal format of timstamp?

2011-12-29 Thread Lars Gustafsson
Hi,

I am trying to recover a lot of deleted rows from a database  ( pg 8.2.3 ) , 
not my database, I promise…..

When using the tool pgfsck I get good results, but timestamp is not implemented.

When trying to export as int8  i get   fx.  4735129360236469258   representing  
 december 29, 2011, 16:30  

But how should I do the conversion from the numeric value to the actual 
timestamp ?

Regards,
Lars.
