Can any body talk me how many transactions make postgres in a second?

It depends on many things
1) speed of hardware/OS/number of disks/type of disks, if you use RAID or not ...
2) number concurrent access
3) size of processed data in one transaction
4) database model

It not possible determine. You must take some machine and perform some own test.

I’m very interesting in this data, because I want to use postgres for a real time database for process control.

I'm not sure if postgres is good database for real time application. You need know maximal response time for realtime application and I afraid that postgres is not good choice for RTA. (MySQL, Firebird, Oracle ... have same limitation ...)
