Can you show us the exact command, with arguments, that you are using? Also what is the size of the dump file you are creating?
The output of pg_dump is received by another process that copies it (and some other data) into a zip file. When I extract the db backup from the zip the backup is fine and I can restore it. I have both tried the pg_dump.exe from the 9.5 alpha and a stable 9.4 both generate this warning. When I change the format to plain the warning goes away. When I call pg_dump from the commandline and let it send to standard out and redirect it to a file the warning does not occur but it does occur when I redirect to nul. Is there a way to prevent this warning? I would think pg_dump shouldn't call ftell on a pipe. Regards, Eelke
