In fact, the Postgresql project has now declared that point releases incrementing the minor (ie. second part) version number will not need a dump/restore any more. So long as you're using PostgreSQL 9.3 or above. Using replication for upgrades means you have to use trigger based replication ie. Slony -- that's the only replication style that allows different versions either end. Unless you're running at least 9.3, where you can upgrade a streaming replication setup without having to stop, upgrade both ends and restart. Even so, this does not affect the library dependencies for the postgresql binaries. The requirement there is minimally that the library ABI version should not change. I don't know what their policy is -- either forwards + backwards ABI compatibility, or (like the FreeBSD project) forwards compatibility, so a program compiled on FreeBSD 9.0 will work on 9.1, 9.2 etc. but one compiled on 9.2 will not necessarily run on 9.0. The pkg(8) system takes a conservative approach and forces you to install exactly the same versions as used for compilation. The new solver in 1.3 may allow some lattitude in this, but we don't have support for dependencies on ranges of version numbers yet. There's a GSoC proposal to implement that which we're waiting on a decision about. Cheers, Matthew --=20 Dr Matthew J Seaman MA, D.Phil.
