Well, "sql" is a query language, and "plsql" is a procedural language,
so I'm guessing you mean MS-Sql Server and PostgreSQL.
A full comparison of the various databases would be a long report, and
is the sort of thing you pay thousands of pounds for. Also, this being a
PostgreSQL group, you'd expect more knowledge of that platform and even
some bias towards it.
You also don't mention what platform/application types/budget you are
looking at.

They all are, for some definition of "RDBMS" - see
http://www.dbdebunk.com for why some people think the term is horribly
abused.

In what sense?

This is an Oracle language. PostgreSQL has something similar plpgsql.

Apart from some of "MySQL's gotchas" (google for the term), they should
all be equivalent, assuming you mean what I think you mean.

Depends what you mean.

Not sure what you mean here.

Depends what products you are interested in.

Not sure what you mean here.

You'd hope all would be reliable on good hardware.
Sorry if this isn't as much help as you'd like, but you'll need to give
more detail if you want a more detailed answer.
