I did that. The following breakpoint occurred again before an error
message from the process on the terminal:
Breakpoint 1, 0x0827eef6 in errfinish ()
(gdb) bt
#0 0x0827eef6 in errfinish ()
#1 0x0828039c in elog_finish ()
#2 0x082993b3 in MemoryContextAlloc ()
#3 0x0828d437 in pg_mb2wchar ()
#4 0x0811c288 in CreateCopyDestReceiver ()
#5 0x0811ea43 in DoCopy ()
#6 0x081f9d00 in ProcessUtility ()
#7 0x081f6ed9 in PostgresMain ()
#8 0x081f7cac in FreeQueryDesc ()
#9 0x081f84d9 in PortalRun ()
#10 0x081f3b51 in pg_parse_query ()
#11 0x081f5296 in PostgresMain ()
#12 0x081c8a1f in ClosePostmasterPorts ()
#13 0x081c9924 in PostmasterMain ()
#14 0x081823b5 in main ()
It looks the same as the previous one to me.
Regards
Johann
