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.

> 5. security

Depends what you mean.

> 6. use and application

Not sure what you mean here.

> 7. support to thirdparty products

Depends what products you are interested in.

> 8. functionability

Not sure what you mean here.

> 9. operatability

Not sure what you mean here.

> 10. reliability

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.
