Yes, I did. 
Step1
sudo /usr/lib/postgresql/14/bin/pg_dump --file "/home/dismay/uchet/Uchet.backup" --host "server" --port "5999" --username "back" --no-password --verbose --format=c --quote-all-identifiers --blobs  --disable-triggers  --encoding="UTF8" "Uchet"
Step2
Manual DROP/CREATE BASE from template 0 (We have to do this because of the difference in locales Win EDB 'Russian_Russia.1251' <> Debian 'ru_RU.UTF-8')
Step3
sudo /usr/lib/postgresql/14/bin/pg_restore --host "127.0.0.1" --port "5998" --username "back" --no-password --dbname "Uchet" --disable-triggers --format=c --verbose "/home/dismay/uchet/Uchet.backup" 2> "/home/dismay/uchet/uchet_all.log"
