Make numeric form of PG version number readily available in Makefiles.
Expose PG_VERSION_NUM (e.g., "90600") as a Make variable; but for consistency with the other Make variables holding similar info, call the variable just VERSION_NUM not PG_VERSION_NUM. There was some discussion of making this value available as a pg_config value as well. However, that would entail substantially more work than this two-line patch. Given that there was not exactly universal consensus that we need this at all, let's just do a minimal amount of work for now. Back-patch of commit a5d489ccb7e613c7ca3be6141092b8c1d2c13fa7, so that this variable is actually useful for its intended purpose sometime before 2020. Michael Paquier, reviewed by Pavel Stehule
