Your pardon, but I submit that the responder did answer your question. Unfortunately, your question may be meaningless in the context asked.
Specifically, you are asking for an Oracle specific feature, which may not have any direct comparison in another system. Instead, it is better to ask how to accomplish whatever your requirement is in postgres. As an analogy, it's like asking a person who only understands windows how to grep. Their response would be 'huh' ? Instead, if you ask them how to search files for text ...
Given this, you seem to be asking 'how do a keep a hot backup dbms server', and the responder said 'using database replication'. That's the same answer I'd give, with the additional tidbit 'using ha/failover'.
Hope this is what you wanted ! -- Pat

Hi, I was able to migrate the Oracle database to Postgres, including functions, procedures. Thanks to ora2pg script and postgres documentation on porting from oracle to Postgres.
I have now two tuff task. We are running Oracle in stadby mode and apply archive logs at remote place to maintain our DR site. Is there any way I can generate archive logs.?
You would need to look at one of the replication solutions. I don't know lot about them.
I need to know postgres datacrash recovery techniques also. If the database crashes we have around 25Gb of data, is there any way apart from restoring the full back up?
It depends on what kind of crash. If the machine unexpectedly shutdown, then should be able to just start the server back up. If you lost a hard drive then you will need to restore from backup. Note that backing up the data directory while the postmaster is running will not give you a usable backup. You either need to use pg_dump or you need to do a backup while the postmaster is shutdown. There is no point in time recovery available at this time.
