Hello all, I have a strange problem that I can't understand. I have been my PostgreSQL-6.3.2 on Linux-ELF-2.0.34 working without any problem for many months. This morning I can't DELETE anymore. If I try to delete a row from any table I have this message: PGexec() -- Request has sent to backend, but backend closed the channel before responding. This probably means the backend terminated abnormally before or while processing the request. and then the backend dies. I tried every statement as: INSERT UPDATE SELECT DROP TABLE and all of them works but DELETE, I tried also VACUUM without success. PLEASE help me !! Best regards, Jose' mailto:[EMAIL PROTECTED]
