You could simply rename old table, create new one and all in same transaction. No data move required.

Subject: [ADMIN] Table size - optimization
Feedlog is a central area where theres been a lot of data dumped together and the beast has grown.
Whats a better way to design the db table(s) for feedlog so we can get a very large performance gain.
Is there a way we can create a feedlog-history table or yearly tables eg feedlog-2014 and move old data out of the original table so its a kean fast table?
What code would need to change to deal with that?
Some data :
Size: 8 GB
relname | relkind | reltuples | relpages
-------------------+---------+-------------+----------
feedlog | r | 6.60508e+07 | 9974857
Thanks,
Lucas
