I am using postgres 9.5 enterprise edition and postgres 9.5 open source where i want know solution of two problems.
1.How can we restore single database from base backup files only, I don't have pg_dump backup.
Restore the whole thing into a temporary instance of postgres and then pg_dump the database you want.
2.How can we restore single instance on different server where multiple instances are running on the production server.
Once you have the dump from pg_dump, you can restore it wherever you like. Chances are higher for success if the version numbers match or the destination is newer than the source.
