Avoid failures while
fsync'ing data directory during crash
restart (Abhijit Menon-Sen, Tom Lane)
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
Also apply the same rules in
initdb --sync-only. This case is less
critical but it should act similarly.
to show functions'
property, if set (Jeevan Chalke)
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.
