Hi, I don't know if this is the right place to ask this (and I'm sorry if this isn't) but here is a little problem I encountered. I have been using postgres in a redhat linux 6.1 for nearly 6 month and it has been working fine until today. I have a table with a field called 'id' (primary key) that is referenced from other tables. Today I tried to delete one of the rows in this table with the following command (worked fine a few weeks ago) and there's the output. It does that each and every time I try to update the primary key or delete a row. I've stoped and started the postmaster several times of course. testsqc=> DELETE FROM henkilo WHERE id = 12; pqReadData() -- backend closed the channel unexpectedly. This probably means the backend terminated abnormally before or while processing the request. The connection to the server was lost. Attempting reset: Failed. !> Here's the output of the debug channel: 001108.16:31:16.753 [31195] StartTransactionCommand 001108.16:31:16.753 [31195] query: DELETE FROM henkilo WHERE id = 12; 001108.16:31:16.840 [31195] ProcessQuery postmaster: reaping dead processes... postmaster: CleanupProc: pid 31195 exited with status 139 Server process (pid 31195) exited with status 139 at Wed Nov 8 16:31:17 2000 Terminating any active server processes...

Is this a known problem with a solution to it?
