Hi,
I have the same error as described in the post I have found in the
pgsql-general archive, see:
http://archives.postgresql.org/pgsql-general/2007-03/msg01664.php
I have PostgreSQL running for one and half year without any issues until
yesterday. I get this:
PANIC: unexpected hash relation size: 122, should be 4
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
I have PostgreSQL 8.1.5 on SunOS (5.10 Generic_118833-36 sun4u sparc
SUNW,Sun-Fire-V445). So it is not only the Windows matter.
To Postgre developers: what kind of information do you need from me to
help you correcting this bug? Let me know (directly to my email) and
I'll try to do my best to help you.
have a nice day
Vlastik
