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 change the encoding.

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

Using the configuration variable client_encoding. If the client_encoding variable is set, that client encoding is automatically selected when a connection to the server is made. (This can subsequently be overridden using any of the other methods 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_encoding to ...*. Or is this another question?
