Hi Tom,

Managed to get the debugger to work and here are the results, don't understand the results mind :-)

#0  0x08155d55 in proc_exit ()
#1  0x08161c17 in PostgresMain ()
#2  0x0813eee0 in BackendFork ()
#3  0x0813e8d6 in BackendStartup ()
#4  0x0813d1c6 in ServerLoop ()
#5  0x0813cda3 in PostmasterMain ()
#6  0x08110f56 in main ()

Thanks for your help sofar...

p.s. Installed phpPgAdmin and that appears to work fine, don't know if that makes any difference

Something like this:

                PGOPTIONS="-W 30" psql ...
                Use ps to determine PID of backend connected to psql
                gdb /path/to/postgres-executable PID-of-backend
                gdb> break proc_exit
                gdb> continue
                (wait for rest of timeout to expire)
                gdb will report reaching proc_exit breakpoint
                gdb> bt
                ... interesting result is here ...
                gdb> quit

If you've never done this before it will probably take you more than 30
seconds to get into gdb --- adjust the W option accordingly.

                                                  regards, tom lane
