Our application tries to insert data into the database as fast as it can.
Currently the work is being split into a number of 1MB copy operations.
When we restore the postmaster process tries to use 100% of the CPU.
The questions we have are:
1) What is postmaster doing that it needs so much CPU?
2) How can we get our system to go faster?
Note: We've tried adjusting the checkpoint_segements parameter to no effect.
Any suggestions welcome.
