Re: WIP/PoC for parallel backup

Thanks for the patches.

I have verified reported issues with new patches, issues are fixed now. 

I got another observation where If a new slot name given without -C option, it leads to server crash error.

[edb@localhost bin]$ ./pg_basebackup -p 5432 -j 4 -D /tmp/bkp --slot test_bkp_slot

pg_basebackup: error: could not send replication command "START_REPLICATION": ERROR:  replication slot "test_bkp_slot" does not exist

pg_basebackup: error: could not list backup files: server closed the connection unexpectedly

This probably means the server terminated abnormally

before or while processing the request.

pg_basebackup: removing data directory "/tmp/bkp"
