Re: [bug fix] PostgreSQL fails to start on Windows if it crashes after tablespace creation

From: "Asif Naeem" <anaeem.it@gmail.com>
> As you have
followed destroy_tablespace_directories() function, Is there any specific
reason not to use same logic to detect type of the file/link i.e.
“(lstat(linkloc, &st) == 0 && S_ISDIR(st.st_mode))”, It also seems have
more appropriate error message i.e.

Thanks for reviewing and testing the patch.  Yes, at first I did what you 
mentioned, but modified the patch according to some advice in the mail 
thread.  During redo, create_tablespace_directories() needs to handle the 
case where the $PGDATA/pg_tblspc/xxx is not a symlink but a directory even 
on UNIX/Linux.  Please see TablespaceCreateDbspace is(). 
destroy_tablespace_directories() doesn't have to handle such situation.
