It'd be unlikely to be able to tell before reaching the CRC checksum at the end of the file, and it seems likely that it never does reach the end in this usage ... are you allowing the psql run to complete? Even if you are, you might miss gzip's one-line complaint in between all the whining from psql. regards, tom lane
