 Yeah.  I'm really, really, *really* sorry for submitting it in the state
 it was in.  I shouldn't have done that just before moving to another
 country.  I found the problem last night, but couldn't get to a Net
 connection until now.
 
 The problem is in src/bin/psql/common.c, around line 250-335 somewhere
 depending on the version.  The 2nd and 3rd clauses of the while loop
 condition:
 
   (rstatus == PGRES_COPY_IN) 
   (rstatus == PGRES_COPY_OUT))
 
 should of course be:
 
   (rstatus != PGRES_COPY_IN) 
   (rstatus != PGRES_COPY_OUT))

It looks like the regression checks need to use two different formats
depending on if integer-timestamps is being used.

For the normal floating point timestamps, the regression checks are correct
since all timestamps between 4713BC to 5874897AD.

However using a 64 bit integer to represented as number of microseconds since
Jan 1, 2000 gives the following reduced range of 4713BC to about 294277AD.
In order to represent to full range of timestamps for julian day counts from 0
to 2147483647 to the nearest microsecond, you require:
   31 bits for the day
   17 bits for the second
   20 bits for the microsecond
for a total of 68 bits needed to represent the full range of timestamps to
the nearest microsecond.

Suggested fix would be one or more of the following:
   1. Reduce the range tested within the regression checks to what is
  capable for integer timestamps.
   2. Use two different regression checks depending on if integer timestamps
  are in use.
   3. Document the different ranges for timestamps depending on if integer
  timestamps are in use.

Mph.  It fails for me too when I use --enable-integer-datetimes.  Looks

http://archives.postgresql.org/pgsql-committers/2003-02/msg00166.php

It seems to be a problem with signed vs unsigned 8-byte integer
timestamps.  Now that I look at it, the patch actually advertises this:

 When timestamps are stored as eight-byte integers (a compile-time
 option), microsecond precision is available over the full range of
 values. However eight-byte integer timestamps have a reduced range
 of dates from 4713 BC up to 294276 AD.

which seems to make it rather foolish to include horology tests for
dates past 294276 AD.

John, you need to rethink this.  Regression tests that fail with
--enable-integer-datetimes will not do.  Is it even a good idea to claim
a range of dates up to 5874897 AD?  The 8-byte-int representation is
probably the wave of the future.  As such, anything it can't do is
not something we want to commit to supporting.
