Hi list,
somehow it seems that in my pg_xlog directory not all wal files are deleted
after copying them to the archive directory even though the archive_status is
done for all of them.
Is it safe to delete them after they were copied or is it safe to use 'mv' as
archive_command?
Thanks!

I have several columns in my database that are timestamps. My developers are asking me how to split the timestamp so that they can look at either the date or at the time portion.I know I can do a select to_date(now(),'-mm-dd') and it will return the date. However, how do I get the time? Also

The CAST-Operater is your friend:
est=# sel
I believe you would want to cast the field
to a date like so select datefield::datefrom table1 or select datefield::time from
table1.

Casting is the better option, but the to_date format spec handles a lot
more than just dates. See:

Hi list,
i have a table with a column where the default value is current_timestamp, but
somehow all the tuples (around 8.000.000) have the same timestamp, which is,
honestly speaking, not what i intended to do. So is the current_timestamp
function only executed when the insert statement starts?
