From 6f58115dddfa8ca63004c4784f57ef660422861d Mon Sep 17 00:00:00 2001

Subject: Measure the current transaction time to milliseconds. Define a new
 function, GetCurrentTransactionStartTimeUsec() to get the time  to this
 precision. Allow now() and timestamp 'now' to use this higher precision
 result so  we now have fractional seconds in this "constant". Add timestamp
 without time zone type. Move previous timestamp type to timestamp with time
 zone. Accept another ISO variant for date/time values: yyyy-mm-ddThh:mm:ss 
 (note the "T" separating the day from hours information). Remove 'current'
 from date/time types; convert to 'now' in input. Separate time and timetz
 regression tests. Separate timestamp and timestamptz regression test.
