This option makes pipelines return as status the value of the last (rightmost)
command to exit with a non-zero status, or zero if all commands exit

pg_dumpall | gzip
Previously, there were many indentation styles in use: Real tabs, 2, 3
or 4 spaces, mixing these within the same file, function or even within
a single line.
This commit changes all bash scripts in the handlers, src and lib dirs
to use consistent indentation: three spaces are now used everywhere.
Other files (e.g. Makefiles) are left untouched.
Additionally, this commit removes all trailing whitespace.
