Re: BUG #15278: When initialising Streaming Slave if some folders and files are symlinks they are not copied over

Hi Michael 
I was assuming that too.
I will consider to move pg_clog back.

That's unsafe for pg_clog as this tracks the transaction commit status
based on the transaction ID.  Note that this is not a bug, a base backup
using the replication protocol allows only symlinks to be in pg_tblspc,
and pg_wal (pg_xlog for <= 9.6) is handled as a special case.
