如何在Ubuntu 13.04上的Postgresql中更改数据目录

Question

I am having a problem changing the data directory on postgresql 9.1 on ubuntu 13.04:

I first did a:

sudo pg_dropcluster --stop 9.1 main

and then attempted to create a new one in the desired path:

 sudo pg_createcluster -d /home/fccoelho/Documentos/databases/postgresqldata 9.1 main

but i fails with a permission denied:

Creating new cluster (configuration: /etc/postgresql/9.1/main, data: /home/fccoelho/Documentos/databases/postgresqldata/)...
initdb: could not access directory "/home/fccoelho/Documentos/databases/postgresqldata": Permission denied
Error: initdb failed

I should mention That I checked the permissions, tried creating the directory manually and "chowning" to user postgres afterwards, etc. nothing changed the permission denied message.

I also tried to used the initdb binary distributed with POstgresql without success

How do I make this work?

Answer 1

I have found a workaraound, but not really a solution:

I found out I cannot maintain the data directory within my home tree so I created a new directory /home/postgresqldata/ and ran:

sudo pg_createcluster -d /home/postgresqldata/ 9.1 main

and everything worked as expected!!
