samizdat-create-database : patch for postgresql-7.4.7

[boud]

hi samizdat-devel,

createuser in postgresql 7.4.7 has -A instead of -S and does not have -R

IMHO it would be better that the database creation script has a fallback
option in case the user does not have a relatively recent version
of postgresql.

So in this patch, i've put  createuser -AD as a fallback option in case
createuser -SDR fails.

It's not perfect, and not good enough for this to be part of a full
debian install, because if the fallback happens, then although the
sysadmin installing will end up with a postgres database and user, a
careful novice sysadmin might become (unnecessarily) concerned about the error
message given out due to the failure of createuser -SDR. Some people *do*
actually read error messages and worry about them...

(On the other hand, i understand why the -SDR options were introduced - partly
in response to my questions as a novice concerned about what to answer to
the questions about what privileges the user should have.)

Anyway, here's the patch.

cheers
boud
