Once problem I can imagine is someone with a long log_line prefix, like '%t %a|', and assuming that the pipe is the end of the log_prefix arguments. If someone adds a pipe to the application name, log parsing code will assume the %a pipe ends the log_line_prefix, and we have no system of escaping things like pipes in log_line_prefix. Effectively, if you use %a, there is no good way to terminate log_line_prefix with a known unique character. -- Bruce Momjian <[email protected]> http://momjian.us EnterpriseDB http://enterprisedb.com + If your life is a hard drive, Christ can be your backup. + -- Sent via pgsql-hackers mailing list ([email protected]) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
