What alternative are you proposing? Failing to start the server doesn't
seem like an attractive choice.
why not? we do error out in a lot of other cases as well... Personally I
find a hard and clear "something is wrong please fix" much more
convinient than defaulting to something that is more or less completely
arbitrary but well...
I would consider the failure to make sense of the registry on windows or
failure to figure timezone information out a more serious issue than a
mere "WARNING" because depending on how you look at the issue it might
actually cause silent data corruption.
Somehow, if you're running a database on windoze, I doubt your data
integrity standards are that high. In any case I'd rather get a bleat
about "why is the server running in GMT" than "my database won't start".
The former will be a lot easier to narrow down.
heh - except that we fail in that department - The only (not really
useful hint) that pg logged was:
"WARNUNG: could not query value for 'std' to identify Windows timezone: 2"
which says nothing about "I failed to figure something sane out and so I
have to fallback to GMT" (which is what the !WIN32 code path seems to be
actually doing but not the WIN32 code).
And even from the vendor perspective getting a support call on "uhm the
database for your app is not starting what logs should I look at" seems
better than "hmm we are now 2 weeks in production and just noticed that
all the timestamps are off by a few hours how can we fix our data?".
PostgreSQL is bundled with a lot of apps on windows these days so the
enduser might not even aware of it (and look into the eventlog only to
find a rather oddly phrased WARNING) unless it fails hard...
