Обсуждение: createdb confusion

man creatdb says -D supposed to be specify the
alternative location

I try (as postgres user)

$ createdb -D /bla bla

and it says

    absolute path are not allowed.

Then I read man initlocation.  The example
I see is

$ initlocation /opt/postgres/data
$ createdb -D /opt/postgres/data/testdb testdb

so I do the same and it fails with the same reason

Does anyone have any idea?

thanks

I am using 7.1.2 on red hat 7.1

I compiled postgres myself

How about:

export PGDATA2=/opt/postgres/data
initlocation PGDATA2
createdb -D PGDATA2 mydb

I haven't created databases in alternate locations, so I'm just
going by the manual. ;-)

Well. I just did this by hand. I did this:

As postgres:

export PGDATA2=/opt/postgres
initlocation PGDATA2

As root, I stopped the postmaster (which was installed via RPMS):

/etc/rc.d/init.d/postgresql stop

In X-Term #1 as postgres:

export PGDATA2=/opt/postgres
postmaster -D /var/lib/pgsql/data

In X-Term #2 as postgres:

createdb mydb -D PGDATA2

And it worked. Apparently, you must define the environmental
variable used in the context of the postmaster session for it to
work.

Hope that helps,

Note also that the environment variable PGDATA2 must be defined in the
*postmaster*'s environment, not only your shell environment.  This is
a crude (and ugly) way of letting the DBA control which directories may
be used as alternate locations --- only what he's listed in the
postmaster's environment may be used.
