function body (and other properties) as a function in the language
is created.  This generalizes ad hoc code that already existed for
the built-in languages.

The validation now happens after the pg_proc tuple of the new function
is created, so it is possible to define recursive SQL functions.

Add some regression test cases that cover bogus function definition
attempts.

I took the opportunity to remove the pg_proc.proistrusted field.

GUC support.  It's now possible to set datestyle, timezone, and
client_encoding from postgresql.conf and per-database or per-user
settings.  Also, implement rollback of SET commands that occur in a
transaction that later fails.  Create a SET LOCAL var = value syntax
that sets the variable only for the duration of the current transaction.
All per previous discussions in pghackers.

underlying function; but cause psql's \do to show the underlying
function's comment if the operator has no comment of its own, to preserve

Re-add warning if the locale prevents LIKE-optimization.  Done within
initdb now.

to reset session userid to the originally-authenticated name.  Also,
relax SET SESSION AUTHORIZATION to allow specifying one's own username
even if one is not superuser, so as to avoid unnecessary error messages
when loading a pg_dump file that uses this command.  Per discussion from
several months ago.
