Обсуждение: createdb -- alternate locations
Hello: Novice, just installed PGSQL 7.0 on Redhat 6.1. Everything went smoothly with initial installation and db setup. However, I've run into some problems subsequently. To keep it simple, here is a specific problem. Attempting to create a database in an alternate location, I went through the following steps as the superuser (postgres): mkdir /home/postgres/testdata export PGDATA2=/home/postgres/testdata initlocation PGDATA2 createdb testdb -D 'PGDATA2' the last command failed with this error: "The database path 'PGDATA2' in invalid. This may be due to a character that is not allowed or because the chosen path isn't permitted for databases" I also tried createdb -D 'PGDATA2' testdb, same result. Any ideas what I'm doing wrong? Thanks, J.R. Belding jrbelding@yahoo.com

> Try createdb -D $PGDATA2 testdb I will be surprised if that works. The initlocation manual says -D can be a path or an environment variable which will be referenced.

OK, I see this in the code, so it seems $PGDATA2 and 'PGDATA2' are the
same:
if [ "$?" -ne 0 -a ! -d "$Location" ]; then
PGALTDATA=`printenv $Location 2> /dev/null`
if [ -z "$PGALTDATA" ]; then
echo "$CMDNAME: environment variable $Location not set"
exit 1
fi
Does everyone have printenv? I sure hope so.

I don't have a POSIX standard handy right now but I don't think it is specified there either. On the other hand, my NetBSD manual page says printenv was introduced in BSD 3.0, so perhaps it's everywhere even if non-standard, which would be typically Unix! If someone does find a platform that is missing printenv it's easy enough to change that code to use env and grep instead. Regards, Giles

What a coincidence; I just asked about this last week. What you've got is right, but before you can createdb, you've got to stop and restart the postmaster with "PGDATA2=/home/postgres/testdata" in its environment.

OK, I have udpated initlocation manual pages to mention stop/restart of postmaster and that this must be defined everytime the postmaster starts. Do we allow absolute paths in initlocation anymore?

That is, shut it down, export xxx, restart. Not ideal, I know, but we're working on it. > > the last command failed with this error: > "The database path 'PGDATA2' in invalid.
