How to speed up insert in postgresql?

Question

PostgreSQL

Tell me, please, what am I doing wrong?
In postgresql 9.4 with default
CREATE TABLE "ds_citizens" (
"citizen_id" bigint NOT NULL DEFAULT '0'
);
INSERT 1000 rows takes 5 sec while in sqlite3 it takes 0.1 sec

Answer 1

# /etc/postgresql/9.5/main/postgresql.conf
fsync = off
synchronous_commit = off
full_page_writes = off

Answer 2

Try using the COPY
construct
