Обсуждение: Mentioning Slony in docs
IMHO it would be appropriate to provide better links to Slony from within the Postgres docs. The main reason is that Slony is Copyrighted PGDG, so we own the code and it is of course BSD licenced. Now that this has been highlighted to me, I can't see a reason for the previous balanced approach. -- Simon Riggs 2ndQuadrant http://www.2ndQuadrant.com

Why is that a reason for mentioning it more prominently? Is "code ownership" a relevant property? -- Peter Eisentraut http://developer.postgresql.org/~petere/

It's not, I'm assuming you'd actually like to see it more prominent. My understanding was that we were trying to show equal favour to all of the various solutions. This was a reason not to do that. -- Simon Riggs 2ndQuadrant http://www.2ndQuadrant.com

The reason for taking a "balanced approach" is that no one solution fits everyone's needs. I don't think the core docs should be pushing Slony more than other solutions. regards, tom lane

We do mention Slony for in-place upgrades because if its capabilities to work across Postgres versions. -- Bruce Momjian <bruce@momjian.us> http://momjian.us EnterpriseDB http://postgres.enterprisedb.com + If your life is a hard drive, Christ can be your backup. +

As an aside, how can copyright be assigned to a non-defined group (a concept really, as near as I can tell). Is the PGDG actually defined anywhere yet? If not, anyone want to take a stab at it? IMHO, we need to get this resolved at some point - either have the code owned by their respective contributors (e.g. Linux) or by a legal entity (e.g. Apache Foundation). The former may be what we actually have anyway. Copying to advocacy as someone there may have the answer. - -- Greg Sabino Mullane greg@turnstep.com PGP Key: 0x14964AC8 200711081016 http://biglumber.com/x/web?pk=2529DF6AB8F79407E94445B4BC9B906714964AC8 -----BEGIN PGP SIGNATURE----- iD8DBQFHMyqrvJuQZxSWSsgRAw0hAJ9DD2gwr4nlmeoPNPeifXTloWip6ACgwv9z WQTV1ccmRQ0EBbomxQUxeak= =zng7 -----END PGP SIGNATURE-----

AIUI, in most European countries copyright is considered naturally given rights that you have and that you cannot give away. In the U.S., you can give copy rights away, however you can only do so to a defined legal entity, of which the PGDG is not one. This can change somewhat depending on country and depending upon employer agreements, but since no one is employed by the PGDG, it's mostly moot from what I can tell. -- Robert Treat Build A Brighter LAMP :: Linux Apache {middleware} PostgreSQL

I'm pretty sure Skytools/Londiste works across versions too. Presumably, any replication that's not based on binary format should work. -- Decibel!, aka Jim C.
