问题
I keep on getting the above error whenever I run the following command via a postgres user.
/usr/lib/postgresql/9.3/bin/pg_upgrade \
-b /usr/lib/postgresql/9.1/bin/ \
-B /usr/lib/postgresql/9.3/bin/ \
-d /var/lib/postgresql/9.1/main \
-D /var/lib/postgresql/9.3/main
cannot write to log file pg_upgrade_internal.log Failure, exiting
I'm using Ubuntu 13.10. Both Postgresql 9.1 and 9.3 are running properly.
回答1:
Make sure that you run this command from a directory that is writable by the postgres
user, like /tmp
or /var/lib/postgresql
:
$ cd /tmp
$ usr/lib/postgresql/9.3/bin/pg_upgrade ...
