Having heard nothing on the list yet about the reported unsuccessful
parallel regression tests on Cygwin with 7.2b3, I thought I'd have a play
myself having found a spare few minutes.

System: Windows XP Professional, PIII 850MHz, 512Mb RAM, 32Gb disk
uname -a: CYGWIN_NT-5.1 PC20 1.3.3(0.46/3/2) 2001-09-12 23:54 i686 unknown

Sequential regression tests pass repeatedly.

Parallel regression tests appear to fail almost randomly. The best I got so
far was 3 failures (out of 79 tests), the worst was about 15. In particular
the horology & misc tests always seems to fail, whilst the others vary. With
the exception of the misc test, all failures appear to be due to failed
connections eg:

--- 1,3 ----
! psql: could not connect to server: Connection refused
! 	Is the server running on host localhost and accepting
! 	TCP/IP connections on port 65432?

The misc test fails with:

*** ./expected/misc.out	Wed Dec 12 20:34:59 2001
--- ./results/misc.out	Wed Dec 12 21:52:29 2001

  --SELECT name(equipment(hobby_construct(text 'skywalking', text 'mer')))
AS equip_name;
  SELECT hobbies_by_name('basketball');
--- 649,658 ----
   timestamp_tbl
   timestamptz_tbl
   timetz_tbl
   toyemp
   varchar_tbl
   xacttest
! (89 rows)
  
  --SELECT name(equipment(hobby_construct(text 'skywalking', text 'mer')))
AS equip_name;
  SELECT hobbies_by_name('basketball');


Though again, this varies with each run - looking at misc.sql I assume that
this is because of the earlier failures?

I have no idea what's causing these connection failures, but if anyone else
has any ideas and would like me to try out anything please let me know -
assuming of course it's not too late for 7.2 yet... 

Regards, Dave.
