The Postgres Pro 10.2.1 sources can be obtained from the
download section of our
website: https://postgrespro.com/products/download. You
should get a file named postgrepro-10.2.1.tar.gz
or postgrespro-10.2.1.tar.bz2. After
you have obtained the file, unpack it:
gunzip postgrepro-10.2.1.tar.gztar xf postgrepro-10.2.1.tar
(Use bunzip2 instead of gunzip if you
have the .bz2 file.)
This will create a directory
postgrepro-10.2.1 under the current directory
with the Postgres Pro sources.
Change into that directory for the rest
of the installation procedure.
You can also get the source directly from the version control repository, see Appendix J.
