psql
create extension pg_bulkload;
CREATE TABLE hello(name text); INSERT INTO hello(name) values('hello'),('world');
COPY hello to '/tmp/hello_copy';
./pg_bulkload -i /tmp/hello_copy -O hello -h 127.0.0.1 -U postgres -d postgres
[root@laptop pg_bulkload]# cd bin/
[root@laptop bin]# ./pg_bulkload -i /tmp/hello_copy -O hello -h 127.0.0.1 -U postgres -d postgres
