[Pkg-postgresql-public] Bug#838641: pg_renamecluster doesn't rollback on failure

[Petr Cech]

Package: postgresql-common
Version: 175
Severity: normal

Hi,
I was renaming cluster maincrc to main, but forgot to move old data directory. The script has detected, that an old dir is there, but the config directory in /etc was already renamed.

I think, that upon failure the renaming of the config directory should be rolled back.

On a side note, the script should also rename the new 9.6 setting `cluster_name'.

Regards
Petr
