I would expect that the age of Template0 is increasing at the same rate as every other database in your cluster. Transaction IDs are global across all databases in the cluster, so as I understand it, executing a transaction in any database will increase the age of all databases by 1.
Hi,
Postgres Version used is 8.1.3
OS: Linux
'SELECT datname, age(datfrozenxid) FROM pg_database'
postgres | 1575
xyz | 1073743934
template1 | 1632
template0 | 61540256
This is the command which I tried and got the above output, and the number is increasing pretty fast for template0.
Please let me know if this a problem.
Regards,
Nimesh.

Hi,
first of all: there is no need to cross post on 4 lists.
If you have a performance problem, post on pgsql-performance.
Second, please tell us which version of PostgreSQL on
which operating system you're using. Diagnosing your
problem might depend on which OS you use...
Finally, explain what you mean by "the age of template0 is
increasing very rapidly", you mean "the size is increasing"?
Bye,
Chris.
