determining when a database was created

[Ian Lipsky]

is there a way to tell when a database was created? I've tried looking in
some of the postgres system tables but i didnt see any that looked like it
had a creation date.

I would have also looked at the date the data folder for the database was
created, but i didnt know which folder belonged to which database.

Is there a way to find out the date the db was created? thanks

Nope, PG doesn't record that anywhere.

You could get an upper bound by looking for the oldest file mod time in
the database's files. This isn't completely reliable, but unless you're
in the habit of changing system catalogs as obscure as pg_am, it'd
probably be good enough.

How can i determine which directory contains the database files? there are a few databases. I
though of doing that, but didnt know how to tell which directory belongs with which database.

thanks

The database directory names correspond to the OID column of
pg_database. So:

SELECT datname, oid from pg_database;

(BTW, this is likely to change in 7.5 if tablespaces get done.)

See also the contrib/oid2name tool.

No doubt Oracle Corp. would be pleased to assist you with this question.
I'm not sure why you expect a bunch of Postgres people to know the
answer, though.

TIP 2: you can get off all lists at once with the unregister command
(send "unregister YourEmailAddressHere" to ***@postgresql.org)
