Tom Lane d08741eab5 Restructure the key include files per recent pghackers discussion: there 
are now separate files "postgres.h" and "postgres_fe.h", which are meant
to be the primary include files for backend .c files and frontend .c files
respectively.  By default, only include files meant for frontend use are
installed into the installation include directory.  There is a new make
target 'make install-all-headers' that adds the whole content of the
src/include tree to the installed fileset, for use by people who want to
develop server-side code without keeping the complete source tree on hand.
Cleaned up a whole lot of crufty and inconsistent header inclusions.

DESCRIPTION

  Here are various cryptographic and otherwise useful
  functions for PostgreSQL.

    encode(data, type)
        encodes binary data into ASCII-only representation.
	Types supported are 'hex' and 'base64'.

    decode(data, type)
    	decodes the data processed by encode()

    digest(data::text, hash_name::text)
	which returns cryptographic checksum over data by
	specified algorithm. eg

	> select encode(digest('blah', 'sha1'), 'hex');
	5bf1fd927dfb8679496a2e6cf00cbe50c1c87145

    digest_exists(hash_name::text)::bool
	which reports if particular hash type exists.

  If any of arguments are NULL they return NULL.

HASHES

  For choosing library you must edit Makefile.

  standalone (default):
	MD5, SHA1

	(the code is from KAME project.  Actually I hate code
	duplication, but I also want to quarantee that MD5 and
	SHA1 exist)

  mhash (0.8.1):
	MD5, SHA1, CRC32, CRC32B, GOST, TIGER, RIPEMD160,
	HAVAL(256,224,192,160,128)

  openssl:
	MD5, SHA1, RIPEMD160, MD2

  kerberos5 (heimdal):
	MD5, SHA1
