Обсуждение: RE: initlocation and createdb

Thank you.  This works, and is close to what I need, but if I don't launch
the postmaster from a window with PGDATA2 defined, such as is done with
"/etc/init.d/postgresql start" or on a system boot, then it doesn't work.  I
tried to export PGDATA2 within /etc/init.d/postgresql, but that didn't work
for me.

Can I make this work from within /etc/init.d/postgresql, or do have to start
the postmaster from a shell with the PGDATA2 already defined?

Thanks again.

restart the postmaster & it should work fine.  the environment variable
has to be defined before the postmaster is started in order for the
alternet locations to work.  this has been covered a number of times
recently.  wasn't it also added to the FAQ or some other documentation
not too long ago?

i'm not 100% sure that this works in all environments, but if your
startup script does a "su -l <username> -c ...", that's likely your
problem.  on the systems that i'm familiar with, the -l flag on su will
reset the environment & read the shell startup files (e.g., .profile).
so if you set the variable earlier in the script, it will be cleared out
before the program is actually run.   the .profile should be read when
the su is invoked & then variable should be available to you then.

hope this helps,
