A dump/restore is not required for those running 9.4.X.
However, if you are upgrading from a version earlier than 9.4.2, see Section E.19.
Avoid failures while
data directory during crash restart (Abhijit Menon-Sen, Tom
In the previous minor releases we added a patch to
fsync everything in the data directory after a
crash. Unfortunately its response to any error condition was to
fail, thereby preventing the server from starting up, even when the
problem was quite harmless. An example is that an unwritable file
in the data directory would prevent restart on some platforms; but
it is common to make SSL certificate files unwritable by the
server. Revise this behavior so that permissions failures are
ignored altogether, and other types of failures are logged but do
not prevent continuing.
Also apply the same rules in initdb --sync-only. This case is less critical but it should act similarly.
pg_get_functiondef() to show
functions' LEAKPROOF property, if set
pushJsonbValue() to unpack
jbvBinary objects (Andrew Dunstan)
This change does not affect any behavior in the core code as of 9.4, but it avoids a corner case for possible third-party callers.
Remove configure's check prohibiting linking to a threaded libpython on OpenBSD (Tom Lane)
The failure this restriction was meant to prevent seems to not be a problem anymore on current OpenBSD versions.
