Ravi,
To (attempt to) answer your questions:
1) does the custom archive format of pg_dump needs to be in a file (not pipe) for the pg_restore to seek back &forth ?
Not to my knowledge.
I suspect that the windows “type” command is adding extra “header” information to the file before passing it to pg_restore, therefore the data blocks are in the wrong position – unless anyone can correct me here?
Maybe you could install GnuWin32 (http://gnuwin32.sourceforge.net)? I believe this gives access to the gnu version of “cat” which will allow you to fully emulate Linux.
2) will pg_restore try to do parallel restore of custom archive format dump by default?
I believe it’ll run serially unless specified to do otherwise. Don’t quote me on that though, I may be way off the mark...
Cheers
