[COMMITTERS] pgsql: Fix two thinkos related to strong random keys.

Fix two thinkos related to strong random keys.

pg_backend_random() is used for MD5 salt generation, but it can fail, and
no checks were done on its status code.

Fix memory leak, if generating a random number for a cancel key failed.

Both issues were spotted by Coverity. Fix by Michael Paquier.
