examinable by non-superusers, and use it to protect the recently-added
GUC variables for data directory and config files.  For now I have only
flagged those variables that could be used to deduce something about
the server's filesystem layout, but possibly we should also mark vars
related to logging settings and other admin-only information?

at the top level of the column's old default expression before adding
an implicit coercion to the new column type.  This seems to satisfy the
principle of least surprise, as per discussion of bug #1290.

well be declared to return "void" to save callers the trouble of
checking for errors.

owned by postgres, doing "pg_ctl start" as root could allow a privilege
escalation attack, as pointed out by iDEFENSE.  Of course the postmaster would
fail, but we ought to fail a little sooner to protect sysadmins unfamiliar
with Postgres.  The chosen fix is to disable root use of pg_ctl in all cases,
just to be confident there are no other holes.

NO ACTION check is deferrable.  This seems to be a closer approximation
to what the SQL spec says than what we were doing before, and it prevents
some anomalous behaviors that are possible now that triggers can fire
during the execution of PL functions.

any possible problems from child programs executed by the client app.

getting rid of numerous ad-hoc versions that have popped up in various
places.  Shortens code and avoids conflict with Windows min() and max()
macros.

to make life cushy for the JDBC driver.  Centralize the decision-making
that affects this by inventing a get_type_func_class() function, rather
than adding special cases in half a dozen places.

  -O2 -Wall -Wmissing-prototypes -Wpointer-arith

Check whether the version of GCC we are using supports any of:

  -Wdeclaration-after-statement
  -Wendif-labels
  -Wold-style-definition

And add the supported flags to CFLAGS.

an oversize message, per suggestion from Oliver Jowett.  I'm a bit
dubious that this is a real problem, since the client likely doesn't
have any more space available than the server, but it's not hard to
make it behave according to the protocol intention.

translation work.

statements without necessarily specifying the datatypes of their parameters.
