packages can use to configure their build.

Fix new problems in insert.sgml and create_function.sgml which kept jade

(rather than compile time). For libpq, even when Kerberos support is
compiled in, the default user name should still fall back to geteuid()
if it can't be determined via the Kerberos system.

A couple of fixes for string type configuration parameters, now that there
is one.

 but were missing the "mailto:" prefix.
Fix typo.
Thanks to Neil Conway <nconway@klamath.dyndns.org> for the heads-up.

macros where appropriate (the code used to have several different ways
of doing that, including Int32, Int8, UInt8, ...).  Remove last few
references to float32 and float64 typedefs --- it's all float4/float8
now.  The typedefs themselves should probably stay in c.h for a release
or two, though, to avoid breaking user-written C functions.

take 'em out of pg_operator.  Also remove from scan.l's set of legal
operator characters.  Update documentation.

backwards compatibility with old behavior.

that RAND_MAX applies to them, since it doesn't.  Instead add a
config.h parameter MAX_RANDOM_VALUE.  This is currently set at 2^31-1
but could be auto-configured if that ever proves necessary.  Also fix
some outright bugs like calling srand() where srandom() is appropriate.

updated to new fmgr style.  Deleted hoary old functions for compatibility
with pre-6.1 representations of these datatypes.
