Hi all, This proposal is about add a column "datcreated" on "pg_database" to store the "timestamp" of the database creation.
A couple weeks ago I had a trouble with a PostgreSQL instance, actually our ERP had some strange behaviors with some data loss, but I searched for ERRORs in log files (OS and PG) and I found nothing. Looking at the files and directories in the cluster noticed something strange, the date / time of the file "base/9999/PG_VERSION" (database of our ERP) was different compared to when we create it. So I used the following SQL to check the date / time of creation of the databases in the cluster: fabrizio=# SELECT datname, (pg_stat_file('base/'||oid||'/PG_VERSION')).modification AS datcreated fabrizio-# FROM pg_database; datname | datcreated -----------+------------------------ template1 | 2012-12-26 12:11:53-02 template0 | 2012-12-26 12:11:54-02 postgres | 2012-12-26 12:11:54-02 fabrizio | 2012-12-26 12:12:02-02 (4 rows) This isn't an elegant solution to do that, but worked fine. However, why not we have a column to store this information? Somebody have another idea?
