We too use postgis_version, but only if postgis_lib_version fails, and do a simple sscanf on the result.  As long as the first part of the returned string was major.minor[.build], our code should be OK.

So, provided that postgis_lib_version remains, we should be OK.  If either postgis_lib_version or postgis_version (iif postgis_lib_version failed) returned any non-blank characters before the "major" number, then we would be in trouble.
