Retire xlateSqlType/xlateSqlFunc; all type name translations are now

handled as special productions. This is needed to keep us honest about user-schema type names that happen to coincide with system type names. Per pghackers discussion 24-Apr. To avoid bloating the keyword list too much, I removed the translations for datetime, timespan, and lztext, all of which were slated for destruction several versions back anyway.
