Questions: 1) Both servers are x64?
> yes 2) What installation files(Graphical installer, source,etc)? > postgresql-9.3.0-1-windows-x64 from enterprisedb.com 3) Does the data directory have the config files? > yes however, postgresql b won't start ("not listening")? 4) How are you starting? > pgadmin -> start server 5) What is the exact error message and where are you seeing it? > "server not listening on port 5432" in cmd ('netstat -ab | find "5432"' also returns empty) so i restored postgresql b's old /data/, but it still won't start?! 6) So there was an existing Postgres instance at b? > yes. two installations - a and b. 7) What version was it? > both are 9.3.0-1 from the same installation file (above). fyi, pg_bouncer process was running even after the server shutdown when i did the copy (since size is not an issue, i could copy the entire /postgresql/?).
