Postgres is failing with 'could not open relation mapping file “global/pg_filenode.map” '

Question

I\'m having an issue with my install of postgres in my development environment and I need some help diagnosing it. I haven\'t yet had any luck in tracking down a solution.

Answer 1

I agree about all of the above solutions. I was running Postgres on a server, and the problem was that I was using a PORT number that was used by some other OLDER version of Postgres.

I only needed to change the port.
