16.3. Getting the Source

The PostgreSQL™ 12.8 sources can be obtained from the download section of our website: https://www.postgresql.org/download/. You should get a file named postgresql-12.8.tar.gz or postgresql-12.8.tar.bz2. After you have obtained the file, unpack it:

gunzip postgresql-12.8.tar.gz
tar xf postgresql-12.8.tar

(Use bunzip2 instead of gunzip if you have the .bz2 file.) This will create a directory postgresql-12.8 under the current directory with the PostgreSQL™ 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 I.
