Hi! I'm a new member and new to postgres. beside postgrest user I would also want my student to create their own database in their own home directory. first I issue (under postgrest user) createuser user_id then under that user_id I run initlocation ~/sql/data then I run createdb -D ~/sql/data mydb at this stage I get an error msg as below: ERROR: Unable to create database directory ~/sql/data/base/mydb createdb: database creation failed on mydb. what should I do now? I tried to find it in archives but i can't find it. FYI I'm using postgres v 6.3 running under RedHat. Thanks in advance.
