Postgres vs. Redhat DB

<p><font size="2">I have a couple of questions regarding postgres and what it can handle.</font><p><font
size="2">Situation:</font><br /><font size="2">I am looking a implementing postgres as my main backend for a internal
corp.website.  I will have huge amounts of data (up in the gig).  I would like to have 2 database servers.  One will be
themaster and one the slave.  I will also have two web servers and a development server that will be used for
developmentand moving all data to the other servers.  I am planning to implement vrrp on the web server; either by
routeron daemon.</font><p><font size="2">Questions:</font><br /><font size="2">1. Does postgres handle data grouping
similarto Oracles blobs and/or clobs?</font><br /><font size="2">2. Does postgres support replication or some type of
master/slaverelation? If yes, where can I find docs on implementation.</font><p><font size="2">3. What is the
differencebetween PostgreSQL and RedHat's version?</font><br /><p><font size="2">Thank You,</font><br /><p><font
