* -Add config variable to prevent auto-adding missing FROM-clause tables

Christopher Kings-Lynne

not all SQL identifiers taken from command line arguments.  We decided
years ago that that was a bad idea: identifiers taken from the command
line should be treated as literally correct.  Remove the inconsistent
code that has crept in recently.  Also fix pg_dump so that the combination
of --schema and --table does what you'd expect, namely dump exactly one
table from exactly one schema.  Per gripe from Deepak Bhole of Red Hat.

extensions to support our historical behavior.  An aggregate belongs
to the closest query level of any of the variables in its argument,
or the current query level if there are no variables (e.g., COUNT(*)).
The implementation involves adding an agglevelsup field to Aggref,
and treating outer aggregates like outer variables at planning time.

of an index can now be a computed expression instead of a simple variable.
Restrictions on expressions are the same as for predicates (only immutable
functions, no sub-selects).  This fixes problems recently introduced with
inlining SQL functions, because the inlining transformation is applied to
both expression trees so the planner can still match them up.  Along the
way, improve efficiency of handling index predicates (both predicates and
index expressions are now cached by the relcache) and fix 7.3 oversight
that didn't record dependencies of predicate expressions.

docs that CLIENT/LOG_MIN_MESSAGES now controls debug_* output location.
Doc changes included.

Also clean up wording that command line utils need database access.
