Hi,
Our application requirement demands archiving of records, so that performance/speed of the application is not compromised. So, am looking out/evaluating on various techniques/solutions available for database archiving, in general, for PostgreSQL.
Your question isn't specific enough. What does "not compromised" mean? Every technique for archiving records has some impact on some part of your system. Is a 0.1% impact too much? A 1% impact? A 10% impact? A factor of 2 slowdown?
Do you need real-time archiving, a few minutes delay, or once a month backup?
Do you need a hot standby or records that can be retrieved in a few hours?
You have to describe your needs completely before you can get a meaningful answer.

Few solutions that comes to my mind are:
1) Table partitioning 2) Separate tablespace and/or schema 3) Moving archived records/tables to a different harddisk
Any other suggestions/pointers/solutions are really welcome and appreciated.
NOTE: We're running PostgreSQL v9.1.3 on CentOS5.2
