[pgrouting-dev] PGR-2.0 Tested and working on postgis versions 2.0.3 and 2.1.0beta3dev

[Stephen Woodbridge]

So subject say it all. I have install postgis 2.0.3 and 2.1.0beta3dev on 
my postgresql 9.2.4 server. I had to make some changes to support some 
changes in 2.1.0 and we are good on both versions.

On postgis 2.1.0 they have changed all the function names to 
st_camelCaseFunctionName() from the older style 
st_camel_case_function_name() names and the old names work be an 
annoying NOTICE message is emitted that broke or tests.

So I have added a utility function pgr_versionLess(v1, v2) function that 
can be used like:

if pgr_versionLess(postgis_lib_version(), '2.1') then
   -- use old style names
else
   -- use new style names
end if;

Keep this in mind when you write your wrapper code if you need to 
support multiple version.
