That was fixed some time ago: 2007-05-17 21:20 tgl * src/backend/libpq/: be-secure.c (REL7_4_STABLE), be-secure.c (REL8_1_STABLE), be-secure.c (REL8_0_STABLE), be-secure.c (REL8_2_STABLE), be-secure.c: Remove redundant logging of send failures when SSL is in use. While pqcomm.c had been taught not to do that ages ago, the SSL code was helpfully bleating anyway. Resolves some recent reports such as bug #3266; however the underlying cause of the related bug #2829 is still unclear. Update to a newer release. regards, tom lane
