Getting postgreSQL binaries without third party tools
Is there any other source where I can download only postgreSQL binaries for linux?


You can use BigSQL's command line client for that:

-bash-4.2$ python -c "$(curl -fsSL https://s3.amazonaws.com/pgcentral/install.py)"

Downloading BigSQL PGC 3.3.6 ...

Setting REPO to https://s3.amazonaws.com/pgcentral
Updating Metadata

BigSQL PGC installed.  Try 'bigsql/pgc help' to get started.

-bash-4.2$ cd bigsql
-bash-4.2$ ./pgc download pg10

-bash-4.2$ ll -h

The archive pg10-10.5-1-linux64.tar.bz2 contains the following top-level directories:

pg10/lib/
pg10/init/
pg10/bin/
pg10/include/
pg10/share/


This can also be used to download a ZIP archive for Windows. "Installation" instructions for BigSQL on Windows can also be found in the above link.
