This update for postgresql94 to 9.4.19 fixes the following security issue:

- CVE-2018-10915: libpq failed to properly reset its internal state between
connections. If an affected version of libpq was used with "host" or "hostaddr"
connection parameters from untrusted input, attackers could have bypassed
client-side connection security features, obtain access to higher privileged
connections or potentially cause other impact SQL injection, by causing the
PQescape() functions to malfunction (bsc#1104199).

A dump/restore is not required for this update unless you use
the functions query_to_xml, cursor_to_xml, cursor_to_xmlschema,
query_to_xmlschema, and query_to_xml_and_xmlschema. In this case please see
the first entry of https://www.postgresql.org/docs/9.4/static/release-9-4-18.html
