AFAIK, PostgreSQL and MySQL are from totally different codebases (never
shared any code). PostgreSQL is BSD license and MySQL is now GNU GPL. They
both implement SQL to varying levels of conformance. PostgreSQL has some
object-oriented features, like table inheritance. Try them both and see what
you like, but I think you'll find PostgreSQL more interesting. For instance,
Postgres can load C functions from shared objects and use them as functions
in SQL, user defined aggregates, procedural language call handlers, and to
create user defined data types (and possibly other things). The 7.1 beta has
implemented some great new features, like write-ahead logging (WAL) and
complete support for SQL table joins, among other things. A C project can do
a lot with Postgres.
RPM packages of PostgreSQL are available at:
http://www.postgresql.org/sites.html
You'll have to check redhat.com or do an rpm query to see if it should be or
is installed on RedHat 6.2.
