A dump/restore is not required for those running 9.3.X.
\nHowever, several of the issues corrected in this release could have resulted in corruption of foreign-key constraints; that is, there might now be referencing rows for which there is no matching row in the referenced table. It may be worthwhile to recheck such constraints after installing this update. The simplest way to do that is to drop and recreate each suspect constraint; however, that will require taking an exclusive lock on both tables, so it is unlikely to be acceptable in production databases. Alternatively, you can do a manual join query between the two tables to look for unmatched rows.
\nNote also the requirement for replication standby servers to be upgraded before their master server is upgraded.
\nAlso, if you are upgrading from a version earlier than 9.3.2, see Section E.24.

Avoid crashing if crypt() returns NULL (Honza Horak, Bruce Momjian)
There are relatively few scenarios in which crypt() could return NULL, but contrib/chkpass would crash if it did. One practical case in which this could be an issue is if libc is configured to refuse to execute unapproved hashing algorithms (e.g., \"FIPS mode\"). (CVE-2014-0066)
Document risks of make check in the regression testing instructions (Noah Misch, Tom Lane)
