pgsql: "Annual" pgcrypto update from Marko Kreen: Few cleanups and - Mailing list pgsql-committers

Log Message:
-----------
"Annual" pgcrypto update from Marko Kreen:

Few cleanups and couple of new things:

 - add SHA2 algorithm to older OpenSSL
 - add BIGNUM math to have public-key cryptography work on non-OpenSSL
   build.
 - gen_random_bytes() function

The status of SHA2 algoritms and public-key encryption can now be
changed to 'always available.'

That makes pgcrypto functionally complete and unless there will be new
editions of AES, SHA2 or OpenPGP standards, there is no major changes
planned.
