According to the docs, the output of a copy command should return a COPY count. It turns out this only happens when copying from a file, and not from STDIN.
> Outputs > On successful completion, a COPY command returns a command tag of the form > COPY count > The count is the number of rows copied. > clone_test_rename=# create temp table aaa (field varchar(255)); CREATE TABLE Time: 3.806 ms clone_test_rename=# copy aaa from '/tmp/test.dat'; COPY 3 Time: 0.623 ms clone_test_rename=# copy aaa from stdin; Enter data to be copied followed by a newline. End with a backslash and a period on a line by itself. >> 123 >> 456 >> hello >> \. Time: 8472.305 ms Tested on 9.3.0 Is there another way I can determine the number of rows copied, short of performing a pre and post count? (other than not using stdin, that is).
