Can I use PostgreSQL 8.3.x for OpenStreetMap?

I'm trying to install phpPgAdmin as an XAMPP addon when I encountered an error because the latest ph开发者_StackOverflowpPgAdmin supports upto PostgreSQL version 8.3.x. So I decided to install PostgreSQL 8.3.11 instead of the latest (PGSQL 8.4.x). Will this matter to my OSM application? Thanks!

There are a lot of advantages to Postgres 8.4 over 8.3, and Open Street Map / PostGIS should work on it, so I'd recommend using 8.4 for the Postgres version, and instead grabbing the latest version of phpPgAdmin from the projects github repo (http://github.com/xzilla/phppgadmin), which fully supports 8.4. That will tide you over until the next official phpPgAdmin release, which is scheduled to happen in the next few weeks.

The only link between OSM and postgresql is probably postgis.

Postgis lastest version (1.5.1) requires postgresql >= 8.3, so the answer is no, it won't matter - if, of course, I understood your question correctly.
