Thanks for the hint. That function is cool and it seems to be the
solution of the concluding question in my talk about read-only
databases at pgconf.de 2011!
I'm new to the contrib best practices of Postgres so I did not expect
that a file 'pg_prewarm_v1.patch' contains a brand new stand-alone
extension.
Does pg_prewarm have already a website entry somewhere? I did not find
anything (like here
http://www.postgresql.org/search/?q=pg_prewarm&a=1&submit=Search )
except at Commitfest open patches (https://commitfest.postgresql.org/
).
