Обсуждение: Uninstalled working db by mistake

Hi Howard,

So long as you haven't touched anything else, simply reinstalling the
package should restore your cluster. Debian packages only do
initialization if the data directories are missing.

Just for good measure I would strongly suggest taking a full
file level copy of the datadir before reinstalling the package.

Thanks David,

Unfortunately my cluster wont start - I am not entirely sure on the
state of  postgresql-9.0, this is the output from dpkd --list



rc  postgresql-8.4 8.4.6-0ubuntu1 object-relational SQL database,
version 8.4
rc  postgresql-9.0 9.0.4-1~lucid1 object-relational SQL database,
version 9.0
ii  postgresql-9.1 9.1.20-1.pgdg1 object-relational SQL database,
version 9.1
ii  postgresql-9.2 9.2.15-1.pgdg1 object-relational SQL database,
version 9.2

Does this mean it is removed?

Per the heading printed by dpkg --list, this means the package is in the
removed state, but it's config files are still present. "apt-get install
postgresql-9.0" should be all required.

David,

I owe you a beer. Nay - several drinks of your choice.

David,

May I suggest you choose something like:
Tequila Ley .925 which is a mere $3,500,000
