Обсуждение: --enable-integer-datetimes doc patch

I can't seem to find any documentation on the --enable-integer-
datetimes configure option. Here's a patch that adds a very brief
description to section 14.5 Installation Procedure, which lists the
other config options.

Here's the description:
Use 64-bit integer storage for datetimes and intervals. This
guarantees microsecond precision in datetime calculations.

Well, there is some, but I agree that it ought to be mentioned where
the other config options are listed.  Applied with additions, viz

+          Use 64-bit integer storage for datetimes and intervals, rather
+          than the default floating-point storage.  This reduces the range
+          of representable values but guarantees microsecond precision across
+          the full range (see <xref linkend="datatype-datetime"> for more
+          information).  Note also that the integer datetimes code is newer
+          than the floating-point code, and we still find bugs in it from time
+          to time.
