Hi,

   When I initialize database, pg_xlog direcory takes almost 17 MB size
   Why pg_xlog/WAL takes 17 MB of size while there is no transaction
occurred ?

   What is the content of pg_xlog , If it's only wal file it's must be
blank after on write of transaction on database.

It's the WAL. Files will be 16MB in size and you will have several (I
think 3 is the minimum). If you have a large update that can increase.
See the checkpoint_segments setting if you think that's something you'll
do frequently.

If you are using WAL-based replication you could have lots if the
archive command keeps failing.

I am not using wall based replication ? I no not have frequent & long transaction , need of checkpoints Just want to get what data resides in pg_xlog that it takes 16MB without any transactions.
