our postmaster random seed used from cancel.

things as well:
  * Computes and saves a cancel key for each backend.  * fflush
  before forking, to eliminate double-buffering problems
    between postmaster and backends.

Other cleanups.

condition where the target label is ambiguous.

pg_exec_query().

Bug fixes:

        PreparedStatement.setObject didn't handle short's

        ResultSet.getDate() now handles null dates (returns null rather
        than a NullPointerException)

        ResultSetMetaData.getPrecision() now returns 0 for VARCHAR

New features:

        Field now caches the typename->oid in a Hashtable to speed things
        up. It removes the need for some unnecessary queries to the
        backend.

        PreparedStatement.toString() now returns the sql statement that
        it will send to the backend. Before it did nothing.

        DatabaseMetaData.getTypeInfo() now does something.

 and vica versa for the next operation.
This is reputed to fix inline math optimization troubles in glibc-2.0.x.
Regression tests still pass on libc/i686 machine.  Patch suggested by Matt.

Add coerce_target_expr().

Change ordering of IS_BUILTIN_TYPE() macro to optimize lookup.
Make CASH type _not_ equivalent to INT4.
 CASH is passed by reference rather than passed by value.

 Currently force the type to match the _first_ select in the union.
Move oper_select_candidate() from parse_func.c to parse_oper.c.
Throw error inside of oper_inexact() if no match for binary operators.
Check more carefully that types can be coerced
 even if there is only one candidate operator in oper_inexact().
Fix up error messages for more uniform look.
Remove unused code.
Fix up comments.

 allowed to be used for alternate database locations.
Probably best to default to not allowed, as now, since there are security
 and integrity issues which should be considered carefully before
 opening things up.
Will update docs to discuss this issue.
