In any case, I had some questions:

. is it compatible with PLSQL?

what I know no, but PLSQL has different mechanism for calling procedures. And first of all it knows references to variables.

. can the effect be achieved by assigning to a composite?

yes. I can use record type. But here is problem with less readability

The best of is implementation of CALL statement, where I can transmit values "by" references. But it's not possible in Postgres :-(. I can't to select unambiguously called procedure. "I can, if I accept SQL Server syntax, where caller specify OUT, INOUT, IN flags too". I am unhappy with current situation, and I search good solution. Simultaneous assignment is simplest.
