Hi,
archive_command is 'cp %p /nfslogs/wal/%f'
and no, we are not removing anything from pg_xlog directory.
once old WAL files of pg_xlog directory are archived in
'/nfslogs/wal/' directory then these WAL files are getting generated
with the same name in pg_xlog directory.
my query is Why is this happening ?
please help me with your suggestions.
Regards.
