Yes, I understood and found a bug in my code. And now schema by using "set client_encoding to \"WIN866\";" worked
correctly.Thanks. 

But while I was searching for a solution, I found the documentation and tried it through a variable PGCLIENTENCODING
changethe encoding.

Using PGCLIENTENCODING. If the environment variable PGCLIENTENCODING is defined in the client's environment, that
clientencoding is automatically selected when a connection to the server is made. (This can subsequently be overridden
usingany of the other methods mentioned above.)  

Using the configuration variable client_encoding. If the client_encoding variable is set, that client encoding is
automaticallyselected when a connection to the server is made. (This can subsequently be overridden using any of the
othermethods mentioned above.)

I set environment variable at 'WIN866', as well set the database properties "ALTER DATABASE "DD866" SET
client_encoding='WIN866'".But it did not work. And without *set client_encoding to ...* don't work. 
This mechanism would be more optimal for my project, because now, for each cursor must run the command *set
client_encodingto ...*. Or is this another question?
