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.

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.

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

Gnanam
