Thread: pgsql: Fix pg_strtof() to not crash on NULL endptr.
Fix pg_strtof() to not crash on NULL endptr. We had managed not to notice this simple oversight because none of our calls exercised the case --- until commit 8f427187d. That led to pg_dump crashing on any platform that uses this code (currently Cygwin and Mingw). Even though there's no immediate bug in the back branches, backpatch, because a non-POSIX-compliant strtof() substitute is trouble waiting to happen for extensions or future back-patches.
