The format option of pg_dump enables tar and custom archive file formats in
addition to the default plain-text file containing SQL commands.
When either the tar or custom format are selected the behaviour of database=all is changed to no longer dump a single file via pg_dumpall. Instead pg_dumpall
is called once to export the "global" data (roles & tablespaces) and then
pg_dump is called once for each non-template table in the database.
To support the GZIP and GZIP_OPTS variables in backupninja and to give the
default --rsyncable gzip compression flag a chance at working on a PostgreSQL
backup, the custom output is forced to not use compression. Instead compression
is done via a pipe to gzip. Hopefully this benefits rsync and rdiff-backup
style backups for reduced backup and storage costs that outweigh the
restoration ones.
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.
