      Augment the date/time examples in the User's Guide to reflect the newer · c05f29e8

       capabilities of specifying time zones as intervals per SQL9x.
      Put refentrytitle contents on the same line as the tag.
       Otherwise, leading whitespace is propagated into the product, which
       (at least) messes up the ToC layout.
      Remove (some) docinfo tags containing dates. Best to omit if the dates
       are not accurate; maybe use CVS dates instead or leave them out.

      Restructure representation of aggregate functions so that they have pg_proc · 902a6a0a
      Tom Lane authored
      entries, per pghackers discussion.  This fixes aggregates to live in
      namespaces, and also simplifies/speeds up lookup in parse_func.c.
      Also, add a 'proimplicit' flag to pg_proc that controls whether a type
      coercion function may be invoked implicitly, or only explicitly.  The
      current settings of these flags are more permissive than I would like,
      but we will need to debate and refine the behavior; for now, I avoided
      breaking regression tests as much as I could.

      Revise aggregate functions per earlier discussions in pghackers. · bec98a31
      Tom Lane authored
      There's now only one transition value and transition function.
      NULL handling in aggregates is a lot cleaner.  Also, use Numeric
      accumulators instead of integer accumulators for sum/avg on integer
      datatypes --- this avoids overflow at the cost of being a little slower.
      Implement VARIANCE() and STDDEV() aggregates in the standard backend.
      
      Also, enable new LIKE selectivity estimators by default.  Unrelated
      change, but as long as I had to force initdb anyway...
