Delay streaming replication using a paramter

От

Hi,
Firstly is it possible for me to delay streaming replication using 

wal_sender_delay

or any other parameter.

Secondly is it possible or under what circumstance will a slave get corrupted from the master either a table of a database.

This is the reason i want to find out if it is possible to delay replication incase of any corruption of data not propagating to the slave.

Thanks

No, you can't do delayed replication on streaming. You can do it if you use file based replication only.

I don't understand this question, so I can't answer it. Sorry.

You would like to delay the replication of data from the master to the slave in order to prevent the possibility of corrupted data being sent to the slave?
I don't understand this strategy. Can you explain?
