Hi All

 

For deploying PostgreSQL on Windoz platform, which one is a better option (performance, reliability) ? Thru Cygwin or Paid version from SRA?

 

Any option for hot backup?

 

Thank you

I think SRA's version has better performance because it is a native
Windows version, rather than using Cygwin, and it does threading, rather
than CreateProcess() to start each database session.

Of course, I work for SRA.

I know one person who was quite happy with the windows version from
http://www.dbexperts.net/. He wanted a "spare" PG server but didn't have the
time/inclination to learn how to manage a Linux server.

The pg_dump utility guarantees a consistent snapshot of the database without
having to block updates - is that what you're after?

I asked SRA a month ago or so if they sold outside Japan, and was told
that "they were not ready yet".  Are they getting ready?

If you need performance either get a copy of BSD or Linux and run it on
that, or get the native version (there are a few different native flavors
floating around, not all cost money, not all are supported anymore, you
can find them in this mailing list's archive by searching for native
windows or something similar.

If you just need it to get started, and you'll move your database over to
heavier iron later, then you can likely use the cygwin version fine.  It's
not the fastest, but it works fairly well, it's free, it's used a lot so
there's plenty of folks to ask about it.

Postgresql, in all flavors, has had hot backup as far back as I can
remember, via pg_dump / pg_dumpall.

No, I don't think so.  The original poster had a .hk domain, so I assume
he is in Hong Kong, and they might sell there, but I am not 100% sure.

The big problem is that all the admin tools are only in Japanese, but I
am told they are working on that.

Yeah, that dbexperts version. Copy their dbx.dll to a unix box and run
"strings -a dbx.dll" and you'll see that this is a modified cygwin.dll
without sourcecode. I would be very careful these days in advertising that.
