There was an apparent attempt to limit the target database for pg_restore to version 7.1.0 or later. Due to a leading zero this was interpreted as an octal number, which allowed targets with version numbers down to 2.87.36. The lowest actual release above that was 6.0.0, so that was effectively the limit. Since the success of the restore attempt will depend primarily on on what statements were generated by the dump run, we don't want pg_restore trying to guess whether a given target should be allowed based on version number. Allow a connection to any version. Since it is very unlikely that anyone would be using a recent version of pg_restore to restore to a pre-6.0 database, this has little to no practical impact, but it makes the code less confusing to read. Issue reported and initial patch suggestion from Joel Jacobson based on an article by Andrey Karpov reporting on issues found by PVS-Studio static code analyzer. Final patch based on analysis by Tom Lane. Back-patch to all supported branches.
