If I enter the following syntax from the RHEL command line:
'''sudo su postgres'''
I end up in the bash-4.1 shell. When executing the following command from within the shell: bash-4.1$ pg_dump db_name > /tmp/my_database.sql I am presented with the following error:
pg_dump: [archiver (db)] connection to database "db_name" failed: could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
Not a RHEL user but...
For psql you specify the port but not for pg_dump.
For psql you seem to be switching to the postgres user’s environment but don’t do that for pg_dump.
In short it seems like you need to trace down your O/S environment differences when each command is run.
