[gentoo-user] how to upgrade postgresql under gentoo

Hi.  I have a puzzle regarding upgrading postgresql.  In my recent world
update I went from 9.4_beta2 to beta3, but when I tried to start the
server, it complained that the databases were written with a different
"catalog version" -- whatever that is, and the pg_upgrade tool requires
both old and new binaries to actually upgrade the database.  So as a
temporary measure, I went back to beta2 and things worked again.  So
what the heck are you supposed to do here, I like pg, but this is very
strange to me.

Thanks in advance for any suggestions.
