Source code test data folder don't have CSV files. How to get the CSV file.

[jian he <jian.universality@xxxxxxxxx>]

trying to understand the source code test part.

https://git.postgresql.org/gitweb/?p=postgresql.git;a=blob;f=src/test/regress/sql/copy.sql;h=d72d226f341f42c69ffcb773c4faf53d9e586894;hb=072132f04e55c1c3b0f1a582318da78de7334379

First I can just ignore all the abs_srcdir, abs_builddir.  Since I can type the absolute file path. So till line 125, I know how to do it. 

Then there is the \set filename :abs_builddir '/results/copytest.csv'. There is only data,expected, sql folder. So where is the results folder.

How can I easily get the csv file? (because I don't know that much about  MAKE and C)..
