Hi all,
I am looking for ways to create an archive of records older than 3
months in one of my table, and store these extracted records into a
local database. Does Postgres have any command to do this?
A single command that will copy data to a destination database, and
then delete from the source database?

TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match
I think the problem may be in determining when a record was added to the
table. If there is no 'date added' column as part of your table
specification that you populate when adding a row then is there any way
to determine when a record was added?
If there is a date added (which is a standard I put in all tables I use)
then it should be a fairly straight forward task of doing an INSERT INTO
followed by a DELETE FROM. As for a single command... I'm not aware of
any "INSERT INTO AND DELETE ORIGINAL" variant so it would have to be two
SQL commands, albeit it uncomplicated.
